Folly

Curse

Innate moves it to the top of the draw pile, so it is one of the 5 cards you draw on turn 1 of every combat. It is Unplayable, and Ethereal exhausts it at the end of that turn. Eternal means it can never be removed or transformed. The result is a 4-card opening hand in every fight for the rest of the run. Run modifiers never generate it.

When to take Folly

You never choose it, an event gives it, and it can never leave your deck. Lean into it with exhaust payoffs and draw relics, since it never clogs later turns anyway.
