Doctor Adam

Alchemy (Whenever Dr. Adam attacks or blocks, create a Potion artifact token with "Tap, Sacrifice this artifact: Choose one — Deal 3 damage to any target, or draw a card.")
Toxic Catalyst: (Sacrifice a Potion, target creature an opponent controls gets -X/-X until end of turn, where X is the number of artifacts you control.)
Chemist's Shield: (Sacrifice a Potion, prevent all damage dealt to Dr. Adam this turn.)
