Grenzo, Dungeon Warden + Transplant Theorist + Su-Chi + Ashnod's Altar

Grenzo, Dungeon Warden

Transplant Theorist

Su-Chi

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Su-Chi, adding CC.
2. When Su-Chi dies, it triggers, adding CCCC.
3. Activate Transplant Theorist by paying 2, putting Su-Chi on the bottom of your library from your graveyard.
4. Activate Grenzo by paying 2, putting Su-Chi into your graveyard from the bottom of your library, and then putting it onto the battlefield.
5. Repeat.

This elegant recycling loop turns Ashnod's Altar and Su-Chi into a self-sustaining mana engine, using the altar's sacrifice outlet to trigger Su-Chi's four-mana return upon death. To keep the cycle going forever, Transplant Theorist acts as the vital bridge that constantly tucks Su-Chi safely back onto the bottom of your library from the graveyard, funded seamlessly by the excess mana generated during the process. Finally, Grenzo, Dungeon Warden exploits its own activated ability to instantly cheat Su-Chi right back onto the battlefield from that very bottom position, fueling infinite loops that generate endless colorless mana, death triggers, and sacrifice counts.
