Wayta, Trainer Prodigy + Spitemare + Rite of Passage

Wayta, Trainer Prodigy

Spitemare

Rite of Passage

How it works

1. Deal exactly 1 or 2 damage to Spitemare.
2. Rite of Passage and Spitemare trigger twice.
3. Resolve both Rite of Passage triggers, putting two +1/+1 counters on Spitemare.
4. Resolve the first Spitemare trigger, dealing damage equal to the damage dealt to it to any target.
5. Resolve the second Spitemare trigger, dealing damage equal to the damage dealt to it to itself.
6. Repeat from step 2.

This loop transforms self-inflicted damage into an escalating storm of power and destruction. Once you deal initial damage to Spitemare, its own trigger deals damage back to itself, which feeds right back into the engine. Meanwhile, Rite of Passage harnesses that self-damage to continually pump up your creature's stats. The secret catalyst holding it all together is Wayta, Trainer Prodigy, whose static ability doubles every single damage-triggered ability, turning a finite poke into an endless cycle of infinite damage and infinite +1/+1 counters.
