Dead Man's Drink

Whenever a Creature you control dies, create a treasure artifact token with "{t}, sacrifice this Artifact: Add one mana of any color"
Whenever you sacrifice an artifact, place a soul counter on Dead Man's Drink. Then at the end of turn, remove all soul counters from Dead Man's Drink and return a creature from your graveyard onto the battlefield under your control with converted mana cost equal to the number of soul counters on Dead Man's Drink.
