Altar of Dementia + Combine Guildmage

Altar of Dementia

Combine Guildmage

How it works

1. Activate Combine Guildmage's first ability by paying 1 and tapping it.
2. Activate Altar of Dementia by sacrificing the persist creature.
3. When the persist creature dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Combine Guildmage.
4. Resolve the Altar of Dementia ability.
5. Repeat from step 2.
