Traveling Plague + Phyrexian Altar + Gremlin Tamer

Traveling Plague

Phyrexian Altar

Gremlin Tamer

How it works

1. Cast Traveling Plague by paying 3, attaching it to another creature you control.
2. When Traveling Plague enters, Gremlin Tamer triggers, creating a creature token.
3. Activate Phyrexian Altar by sacrificing the creature Traveling Plague is attached to.
4. When the creature dies, Traveling Plague triggers, returning itself from your graveyard to the battlefield attached to the token created in step 2.
5. When Traveling Plague enters, Gremlin Tamer triggers, creating a creature token.
6. Repeat from step 3.

This clever loop uses Traveling Plague's unusual self-recurring nature to fuel a continuous cycle of sacrifice and creation. By enchanting a creature, you set the stage to sacrifice it to Phyrexian Altar for mana; because Traveling Plague returns to the battlefield whenever its host leaves, it can immediately attach itself right back to the Gremlin Tamer token you just generated. That's where Gremlin Tamer pulls its weight, turning every single re-entry of the Aura into a brand-new Gremlin token to keep the sacrifice engine running indefinitely.
