Wayta, Trainer Prodigy + Bellowing Aegisaur + Cacophodon + Temple Altisaur + Twinflame

Wayta, Trainer Prodigy

Bellowing Aegisaur

Cacophodon

Temple Altisaur

Twinflame

How it works

1. Cast Twinflame by paying its mana cost, creating a token copy of Bellowing Aegisaur.
2. Activate a mana-producing permanent you control by tapping it, adding at least .
3. Activate Wayta by paying and tapping it, causing Cacophodon and the nontoken Bellowing Aegisaur to fight each other, with each only taking 1 damage due to Temple Altisaur.
4. Cacophodon and Bellowing Aegisaur each trigger twice.
5. Resolve all Bellowing Aegisaur triggers, putting two +1/+1 counters on each other creature you control.
6. Resolve both Cacophodon triggers, untapping the mana-producing permanent and Wayta.
7. Repeat from step 2, alternating between having the token and nontoken Bellowing Aegisaur fight Cacophodon.
