Gishath, Sun's Avatar + Mortuary + Aggravated Assault + Thermopod

Gishath, Sun's Avatar

Mortuary

Aggravated Assault

Thermopod

How it works

1. Deal combat damage to an opponent using Gishath.
2. Gishath triggers, causing you to reveal the top seven cards of your library and put all Dinosaurs revealed this way onto the battlefield.
3. Move to your postcombat main phase.
4. Activate Thermopod's second ability five times by sacrificing five other nontoken Dinosaurs, adding .
5. When the Dinosaurs die, Mortuary triggers that many times, putting the Dinosaurs on top of your library from your graveyard.
6. Activate Aggravated Assault by paying 3, causing you to untap all creatures you control and to get an additional combat and main phase after this one.
7. Repeat.

This vicious prehistoric loop starts when Gishath, Sun's Avatar connects with an opponent to flood the battlefield with a pack of rampaging Dinosaurs from the top of your library. Once you move to your postcombat main phase, Thermopod steps in as the sacrifice outlet to feed those fallen beasts into red mana while also satisfying Mortuary, which neatly recycles each sacrificed Dinosaur straight back to the top of your library. From there, the massive mana pool you've generated pays for Aggravated Assault to untap your entire board and grant you an extra combat phase. By sending Gishath, Sun's Avatar back in for another strike, you loop the entire process indefinitely for infinite combat phases, endless damage, and infinite creature triggers.
