Void Attendant + Rest in Peace + Phyrexian Altar + Doubling Season

Void Attendant

Rest in Peace

Phyrexian Altar

Doubling Season

How it works

1. Activate Void Attendant by paying 1 and putting a card an opponent owns from exile into their graveyard.
2. The card is instead put back into exile due to Rest in Peace.
3. Resolve the Void Attendant ability, creating two 1/1 Eldrazi Scion creature tokens.
4. Activate Phyrexian Altar twice by sacrificing the Eldrazi Scions, adding 1.
5. Repeat.

This clever loop turns graveyard replacement effects into a self-sustaining engine by letting Void Attendant repeatedly target cards in exile, which Rest in Peace harmlessly redirects right back to exile to satisfy the activation cost. Meanwhile, Doubling Season supercharges your token generation by doubling the Eldrazi Scions produced each cycle, ensuring you always have more than enough fodder to feed into Phyrexian Altar for the mana needed to keep going. The result is an endless cascade of sacrifices and creature triggers, all fueled by a single activation cost that pays for itself over and over again.
