Wayta, Trainer Prodigy

Bellowing Aegisaur

Cacophodon

Temple Altisaur

Mirror Image

How it works

1. Activate a mana-producing permanent you control by tapping it, adding at least .
2. Activate Wayta by paying and tapping it, causing Cacophodon and Bellowing Aegisaur to fight each other, with each only taking 1 damage due to Temple Altisaur.
3. Cacophodon and Bellowing Aegisaur trigger twice.
4. Resolve both Bellowing Aegisaur triggers, putting two +1/+1 counters on each creature you control.
5. Resolve both Cacophodon triggers, untapping the mana-producing permanent and Wayta.
6. Repeat from step 2, alternating between having Cacophodon fight Bellowing Aegisaur and Mirror Image to ensure neither dies due to lethal damage.
