Grenzo, Dungeon Warden + Soldevi Digger + Su-Chi Cave Guard + Thermopod

Grenzo, Dungeon Warden

Soldevi Digger

Su-Chi Cave Guard

Thermopod

How it works

1. Activate Thermopod's second ability by sacrificing Su-Chi Cave Guard, adding .
2. When Su-Chi Cave Guard dies, it triggers, adding eight C.
3. Activate Soldevi Digger by paying 2, putting Su-Chi Cave Guard on the bottom of your library from your graveyard.
4. Activate Grenzo by paying 2, putting Su-Chi Cave Guard into your graveyard from the bottom of your library, and then putting it onto the battlefield.
5. Repeat.

This clever loop turns your graveyard into a revolving door using Grenzo, Dungeon Warden to constantly pull creatures straight from the bottom of your library. Soldevi Digger acts as the crucial glue, cleanly cycling dead creatures right back to that bottom spot so Grenzo can find them again. Meanwhile, Thermopod provides the necessary outlet to sacrifice Su-Chi Cave Guard, whose generous death trigger supplies more than enough colorless mana to fund the entire sequence while even netting you a bonus red mana along the way.
