Void Attendant + Rest in Peace + Phyrexian Altar + Chatterfang, Squirrel General

Void Attendant

Rest in Peace

Phyrexian Altar

Chatterfang, Squirrel General

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 a 1/1 Squirrel and a 1/1 Eldrazi Scion creature token.
4. Activate Phyrexian Altar twice by sacrificing the Eldrazi Scion and Squirrel, adding 1.
5. Repeat.

This clever loop turns the replacement effect of Rest in Peace into an endless engine by feeding cards right back into exile to fuel Void Attendant's ability. As Void Attendant works its magic, Chatterfang, Squirrel General steps in to double your production, ensuring a bonus swarm of Squirrels tags along beside every Eldrazi Scion. You can then feed both the Scions and the Squirrels directly into Phyrexian Altar to generate all the mana you need to keep the cycle spinning infinitely.
