Was Keen Engineering worth buying?
Yes. The singles are worth more than the deck cost at release.
Keen Engineering cost $29.99 at release. Its singles are worth $48.71 today. That is 1.62× what you paid, since it was released earlier this year.
That is a return over time, not a judgment about the day it launched: the release price in that sentence is from release day and the singles value is from today. An older deck has had longer for its cards to move, which is why age is quoted alongside the multiple.
Card prices as of 2026-10-27. Release price: Wizards of the Coast, verified 2026-09-27.
