Snap

NecrobinderAttackCommon
Osty deals 7 damage.
Add Retain to a card in your Hand.

Osty attacks the target for 7 (10 upgraded), then you pick a card in your hand that lacks Retain and give it Retain for the rest of the combat. If Osty is missing the hit is skipped, but you still get to pick a card. The retained card is not discarded at the end of the turn, on every later turn too.
