Deep-Slumber Titan + Elemental Mastery + Pandemonium

Deep-Slumber Titan

Elemental Mastery

Pandemonium

How it works

1. Give Deep-Slumber Titan indestructible, if needed.
2. Activate Deep-Slumber Titan by tapping it, creating seven 1/1 Elemental creature tokens.
3. When the Elementals enter the battlefield, Pandemonium triggers that many times.
4. Resolve the first Pandemonium trigger, dealing 1 damage to Deep-Slumber Titan.
5. Deep-Slumber Titan triggers, untapping itself.
6. Resolve all remaining Pandemonium triggers, dealing 6 damage divided among any number of targets.
7. Repeat from step 2.

This fiery engine hinges on turning Deep-Slumber Titan's natural sluggishness into an endless loop of explosive creation. By enchanting the slumbering giant with Elemental Mastery, tapping it transforms its massive power into a flood of hasteing attackers—though you'll want to ensure it has indestructible first to survive the self-inflicted blows. Those newly minted tokens immediately trigger Pandemonium upon entry, allowing you to redirect just one point of that damage right back into the Deep-Slumber Titan to wake it up and untap it. The remaining triggers rain infinite damage down upon your opponents while the engine churns out infinite creature tokens and infinite creature ETB triggers, ready to repeat the cycle ad infinitum.
