Deep-Slumber Titan + Elemental Mastery + Warstorm Surge

Deep-Slumber Titan

Elemental Mastery

Warstorm Surge

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, Warstorm Surge triggers that many times.
4. Resolve the first Warstorm Surge trigger, dealing 1 damage to Deep-Slumber Titan.
5. Deep-Slumber Titan triggers, untapping itself.
6. Resolve all remaining Warstorm Surge triggers, dealing 6 damage divided among any number of targets.
7. Repeat from step 2.

This explosive loop transforms the lumbering Deep-Slumber Titan—which naturally refuses to untap during your untap step—into an automated token-factory by enchanting it with Elemental Mastery. Tapping the enchanted creature fires off its activated ability to flood the board with seven hasty Elemental tokens whose count matches its power. Each of those tokens immediately triggers Warstorm Surge upon entering the battlefield, which conveniently redirects a ping right back at the Deep-Slumber Titan to untap it for the next iteration.
