Stable Serum
UncommonSharedDrinkBuff
Gives 2 stacks of Retain Hand. At the end of this turn and the next, your hand is not discarded; each end of turn uses up one stack. It covers every card in hand, not just ones you choose, so a big retained hand means fewer draws next turn. Any player can be the target in co-op.
