Ivy Lane Denizen + Altar of Dementia

Ivy Lane Denizen

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing the creature with persist.
2. The persist ability triggers, returning that creature to the battlefield with a -1/-1 counter.
3. Ivy Lane Denizen triggers, putting a +1/+1 counter on the persist creature.
4. Resolve the ability from step 1, milling target player a number of cards equal to the sacrificed creature's power.
5. Repeat.
