Quintorius, Field Historian

Chishiro, the Shattered Blade

Fiery Mantle

Phyrexian Altar

How it works

1. Cast Fiery Mantle by paying 1, attaching it to any other creature you control.
2. When Fiery Mantle enters the battlefield, Chishiro triggers, creating a 2/2 Spirit creature token.
3. Activate Phyrexian Altar twice by sacrificing the Spirit and the creature that Fiery Mantle is attached to, adding 1.
4. Fiery Mantle triggers, returning itself to your hand from your graveyard.
5. Quintorius triggers, creating a 3/2 Spirit creature token.
6. Repeat.
