Stable Serum

UncommonSharedDrinkBuff
Retain your Hand for 2 turns.

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.

When to take Stable Serum

Use it to hold expensive cards this turn, then play two turns' worth next turn with fresh Energy. Pairs with Ice Cream, but never drink it on a hand of Strikes and Defends.
