Pitiless Plunderer + Builder's Talent + Altar of Dementia

Pitiless Plunderer

Builder's Talent

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing the persist creature.
2. When the persist creature dies, its persist ability and Pitiless Plunderer trigger.
3. Resolve the persist creature trigger, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
4. Resolve the Pitiless Plunderer ability, creating a Treasure token.
5. When the Treasure token enters the battlefield, Builder's Talent's second ability triggers, putting a +1/+1 counter on the persist creature.
6. Resolve the Altar of Dementia ability.
7. Repeat.
