Elder Gloomwraith

When Gloomwraith enters the battlefield, create a Food token for each opponent.
Toxic Waste — Whenever you would create a Food token, instead create a Toxic Waste token under the control of an opponent of your choice. (Toxic Waste tokens are Food tokens with 'At the beginning of your end step, you get a rad counter. You may pay 2 mana to sacrifice this artifact.')
Radiation Feast — Whenever a player sacrifices a Toxic Waste token, draw a card.
