Skritch, Dubious Cleric

Flying
Whenever a creature an opponent controls dies, create a viscera token.
At the beginning of your upkeep choose one —
• Skritch gains infect and gets +1/+0 until end of turn for each viscera token you control.
• Create a 2/2 zombie creature token for each viscera token you control.
• You gain X life where X is twice the number of viscera tokens you control.
