How it works
Activate Yawgmoth by paying 1 life and sacrificing a creature, targeting any creature an opponent controls.
The sacrificed creature dies, triggering Blood Artist, causing an opponent to lose 1 life and you to gain 1 life.
Resolve the Yawgmoth ability, putting a -1/-1 counter on a creature an opponent controls, and causing you to draw a card.
Hapatra's second ability triggers, creating a 1/1 Snake creature token.
Repeat.
You may also repeat this loop whenever a creature enters the battlefield under an opponent's control.
