How to build Prismari, the Inspiration

Prismari, the Inspiration copies each instant and sorcery you cast once for every spell cast before it that turn, your opponents' spells included. So this build casts on their turns, and the copies arrive a few at a time instead of in one long turn of yours.

Art by Justin Gerard

Your opponents' spells raise the count, so most of the copying happens on their turns

Storm looks at every spell cast before it this turn, and it does not ask who cast them. On your own turn you build that number yourself, one cheap spell at a time. On anyone else's turn they build it for you. A player who casts a creature, an equipment and a removal spell before passing has put three spells on the count, and your next instant comes with three copies. Big Score cast then costs four mana and one card from your hand, paid once, and it draws eight cards and leaves eight Treasures. Into the Roil with its kicker paid bounces four permanents and draws four. Neither needed a single spell of yours to get there.

That is why the list is mostly instants, 28 of them against 11 sorceries. The sorceries can join in too. Hypersonic Dragon lets you cast them whenever you could cast an instant for as long as it lives, and sacrificing Emergence Zone does the same for one turn, which is how Crackle with Power or Fiery Confluence lands in someone else's end step with their spells already counted. Rhystic Study pays off the same habit from the other side. Every spell an opponent casts is one more copy for you and, unless they pay, one more card.

This is also the honest answer to a table that does not want to play against storm. What that table objects to is a single turn of twenty spells while everyone else waits. Two or three instants in each opponent's end step copy just as well, take a minute each, and spread the deck's output across the whole round. The core list is built to be played that way, and the bracket 4 rung further down is the version that is not.

Prismari counts herself and every spell before her, so she comes down second

Prismari is a spell while you cast her, so she counts toward the storm of anything you cast after her in the same turn. The spells cast before she arrived count as well. Storm reads the whole turn, not the time since she landed, and all she needs is to be on the battlefield when the instant or sorcery is cast. So the turn she comes down has an order: cheap spells first, then the dragon, then the spell you want copied. Ten mana is Opt, then Consider, then Prismari, then Lightning Bolt, and that Lightning Bolt is the fourth spell of the turn, so it deals 3 damage four times to whatever targets you pick. Cast it first and it gets no copies at all.

The cards that do this best cost little or nothing. Gitaxian Probe can be paid with 2 life instead of mana. Frantic Search costs three and untaps three lands, and each copy untaps three more, so as the third spell of a turn it can hand back nine. Each of them adds one to the count while leaving the mana for the spell that matters, which is what lets the payoff arrive fourth with most of the turn's mana unspent.

The copies are not optional, so there is no Time Warp and no Blasphemous Act

Read the reminder text again and the copies have no “may” in front of them. The only choice is whether to give them new targets. Most Izzet lists never have to care, and this one leaves out two kinds of card because of it.

Extra turns are the first. Bracket 3 allows an extra turn spell as long as you do not chain them, and under Prismari you cannot cast one without chaining it unless it is the first spell anyone has cast that turn. Time Warp cast second takes two extra turns, and cast fourth it takes four. None are in the core list or the budget rung. Time Warp only appears in the bracket 4 rung, where taking turns back to back is allowed.

Damage sweepers are the second. A copied sweeper deals its damage again, Prismari has 7 toughness, and her ward only matters against spells that target her. A four damage sweeper with one spell cast before it hits her for eight, and Blasphemous Act kills her even uncopied. The sweepers in this list never touch your side. Electrickery and Mizzium Mortars cast with overload damage only creatures you do not control, and a copy of an overloaded spell is overloaded too. Electrickery overloaded costs two mana, and as the fourth spell of a turn it deals 4 damage to every creature your opponents control and none to yours. Cyclonic Rift overloaded is the third, and once its first copy resolves the rest find nothing to bounce, which costs you nothing.

Fiery Confluence is the card that needs a rule at the table. Its first mode deals 1 damage to each creature, and a copy cannot change the modes you chose. Pick that mode three times as the fourth spell of a turn and every creature takes twelve, the dragon included. Pick the second mode three times instead and each resolution deals 6 to every opponent, so the same four resolutions deal twenty four to each of them. That is the cleanest kill in the list, and it costs four mana.

Five cards make spells cheaper, and only the two Medallions reach the dragon

Goblin Electromancer, Baral, Chief of Compliance and Stormcatch Mentor each take one mana off every instant and sorcery you cast. None of them helps with Prismari, who is a creature spell. Sapphire Medallion and Ruby Medallion take one off every blue spell and every red spell, and Prismari is both colours at once, so each Medallion counts for her. With both out she costs five, and a second cast from the command zone costs seven rather than nine. That is why they sit in a list that already has three other discounts.

The same split runs through the rest of the mana. Resonating Lute makes every land tap for two, and that mana can only be spent on instants and sorceries. Sol Ring, Arcane Signet, Izzet Signet, Talisman of Creativity, Mind Stone, Fellwar Stone and every Treasure can pay for anything, so those are what put the dragon on the battlefield. Izzet Boilerworks is the one land here that always enters tapped, and it earns that because it makes two mana toward her. Thirty five lands is an ordinary number for an average mana value of 2.48, and it does not drop lower here because nothing on the spell side of the deck helps with the seven.

Storm-Kiln Artist pays in Treasure, and Treasure keeps until your turn

Storm-Kiln Artist makes a Treasure whenever you cast or copy an instant or sorcery, so every copy Prismari makes is also a mana. Archmage Emeritus draws a card on the same condition, and Ral, Storm Conduit deals 1 damage to an opponent. Big Score, Unexpected Windfall and Strike It Rich make Treasure themselves, and so does each copy of them. Sanar, Unfinished Genius makes one more on any turn you have cast an instant or sorcery. Mica, Reader of Ruins turns that Treasure back into spells: each time you cast an instant or sorcery you may sacrifice an artifact to copy it once more, and Treasures and the Soldier tokens from Third Path Iconoclast are all artifacts.

The deck runs Treasure instead of rituals on purpose. Mana from Seething Song or Pyretic Ritual is gone at the end of the step it was made in, so a ritual only helps on the turn you plan to win. A Treasure made in an opponent's end step is still there when you untap, and it pays for Prismari, for a counterspell held up through the next player's turn, or for anything else. A deck that does its copying on other people's turns and spends on its own wants the second kind. The rituals are in the bracket 4 rung, which is where a turn exists to be won.

Veyran doubles Thousand-Year Storm and Storm-Kiln Artist, and leaves Prismari alone

Veyran, Voice of Duality makes your permanents' abilities trigger twice when casting or copying an instant or sorcery is what set them off. Storm is not one of those abilities. It belongs to the spell while it is on the stack, not to a permanent, so Veyran adds nothing to Prismari's copies. What doubles is everything that reacts to them: two Treasures from Storm-Kiln Artist for every cast or copy, two cards from Archmage Emeritus, 2 damage from Ral, and two triggers from Mica on every cast, each able to eat an artifact for another copy. Veyran's own trigger is doubled as well, so it grows by +2/+2 for every cast or copy, and a single Lightning Bolt cast fourth in a turn is worth +8/+8 to it on its own.

Thousand-Year Storm is the exception, because it is an enchantment and its trigger belongs to a permanent. With Veyran out it copies each spell twice over. It is also what the deck leans on while Prismari is in the command zone, and it counts differently. It copies a spell once for each instant and sorcery you have cast earlier in the turn, so creature spells, Prismari herself and everything your opponents cast are left out. On your own turn the two numbers are close. On someone else's it is usually zero, which is why the dragon matters more than the enchantment. Twinning Staff adds one copy to every batch from either of them.

Ward costs 5 life, so the counterspells are saved for sweepers

Prismari's ward asks 5 life of anyone who targets her, and at forty life plenty of players will pay that to kill a seven mana dragon. What ward cannot touch is a spell that never targets: a wrath, an edict, anything that says each or all. Those are what the five counterspells are for. Fierce Guardianship is free while Prismari is on the battlefield and counters any noncreature spell, which covers every sweeper. Swan Song and An Offer You Can't Refuse cost one mana, and Arcane Denial and Counterspell, the two that also stop a creature spell, cost two.

Storm gives a counterspell very little. Its copies need other spells on the stack to point at, and most fights have only one. Two things change that. A countered spell still adds to the count for later in the turn, so an opponent's spell you stopped still puts a copy on your next one. And a copy of a spell is a spell, so An Offer You Can't Refuse can be aimed at copies of your own Opt, giving you two Treasures for each one it counters. It works the other way round too. An opponent who counters your original has not stopped its copies, and each of them has to be countered on its own.

The budget rung keeps the sweepers that spare her, and bracket 4 takes the long turn back

All three lists are built around the same pieces: Prismari, Storm-Kiln Artist, Archmage Emeritus, the cheap card draw, the two one-sided sweepers and Fiery Confluence. What moves between rungs is how much of the protection is free, and whether the deck spreads its copies over the round or spends them in one turn.

Ten swaps make the cheap list, and it comes to $96.82 against the core list's $349.07. Rhystic Study, Fierce Guardianship and Cyclonic Rift are the core's Game Changers, so taking all three out leaves no bracket floor, and the list fits at a bracket 2 table. Rhystic Study becomes Diary of Dreams, which only counts the spells you cast, so a busy table stops paying you cards. Fierce Guardianship becomes Negate, two mana you have to leave open instead of none. Cyclonic Rift becomes Echoing Truth, a two mana bounce spell whose copies each take another permanent, though it no longer clears a board. Ruby Medallion becomes Thunderclap Drake, a discount on spells only, so with Sapphire Medallion alone the dragon costs six. Crackle with Power becomes Jaya's Immolating Inferno, a legendary sorcery this deck can always cast once Prismari is out, and before that off Veyran, Baral, Sanar, Mica or Ral. Snapcaster Mage becomes Archaeomancer and Twinning Staff becomes Tablet of Discovery, while Steam Vents, Otawara, Soaring City and Swan Song make way for two lands that enter tapped and Saw It Coming. The cheap list plays the same game with fewer free answers and a dragon that costs one mana more.

The bracket 4 rung is the long turn this page has been steering around, and it costs $523.69. Jeska's Will, Underworld Breach and Mana Vault join the core's Game Changers for six, which rules out bracket 3 on its own. The rest of the swaps change what a turn is for. Seething Song, Pyretic Ritual and Desperate Ritual are mana that only matters now, and under Prismari a ritual makes its mana once for every resolution. Seething Song cast with three spells before it adds twenty red for three. Jeska's Will copies the same way, and each copy can name a different opponent's hand and exile three more cards to play. Grapeshot and Brain Freeze carry storm of their own, so with Prismari out each one is copied twice for every spell before it. Underworld Breach makes the graveyard castable again, so the count keeps climbing after the hand runs out. Goldspan Dragon makes every Treasure tap for two, which doubles what Storm-Kiln Artist pays per copy. Mana Vault brings the dragon down a turn sooner. Time Warp, left out of both other lists, becomes as many extra turns as the spells before it plus one, and only this rung allows that.

What this rung gives up is the pacing that makes the core list welcome. It wants one turn of its own with every spell in it, and it belongs only at a table that has agreed to sit through that.

FAQ

Does Prismari, the Inspiration count spells my opponents cast?

Yes. Storm copies a spell once for each spell cast before it that turn, and it counts every player's spells, countered ones included. Prismari only gives storm to the instants and sorceries you cast, but the count behind each one is the whole table's. That is why this build keeps mana open and casts late in other players' turns.

Does Prismari copy creature spells?

No. Only your instants and sorceries get storm, so Prismari herself and every creature you cast are never copied. They still add to the count. Cast her and then an instant in the same turn, and the instant is copied at least once.

Does Veyran, Voice of Duality double Prismari's storm?

No. Veyran doubles abilities that belong to permanents, and storm belongs to the spell. It does double what the copies set off, so Storm-Kiln Artist makes two Treasures and Archmage Emeritus draws two cards for every copy. It also doubles Thousand-Year Storm, which is an enchantment.

If an opponent counters my spell, are the storm copies countered too?

No. Each copy is a separate spell and has to be countered on its own, so a counterspell aimed at the original leaves every copy where it is. The countered spell also still adds to the count for anything you cast later that turn.

What bracket does a Prismari, the Inspiration deck belong in?

Bracket 3 for the list on this page. Rhystic Study, Cyclonic Rift and Fierce Guardianship are Game Changers, three is the most bracket 3 permits, and the budget rung removes all three for a list with no floor. Prismari also settles something the floor does not show. An extra turn spell cast after any other spell becomes a chain of extra turns, which is not allowed below bracket 4, so neither of the lower lists runs one.

How much does a Prismari, the Inspiration deck cost?

$349.07 for the core list on 23 October 2026, buying the cheapest printing of every card. Rhystic Study at $67.29, Fierce Guardianship at $61.18 and Cyclonic Rift at $29.13 add up to nearly half of that. The budget rung swaps those three and seven more for $96.82, and the bracket 4 rung comes to $523.69, with Mana Vault covering more than half the difference.

Is Prismari, the Inspiration in a Secrets of Strixhaven precon?

No. Rootha, Mastering the Moment leads the set's blue and red Commander deck, and it turns the single biggest spell you cast each turn into a flying Elemental of that size. Prismari, the Inspiration is a card from the main set, not the Commander decks, and it wants the reverse: a stack of cheap spells rather than one large one. The upgrade guide for Rootha's deck is linked below.
