How it works
Cast Mighty Mutanimals by paying 2.
When Mighty Mutanimals enters, its first ability triggers, creating a 2/2 Mutant creature token.
When the Mutant enters, Mighty Mutanimals' second ability triggers, putting a +1/+1 counter on Herd Baloth.
Herd Baloth triggers, creating a creature token.
When the creature token enters, Mighty Mutanimals' second ability triggers, putting a +1/+1 counter on Herd Baloth.
Repeat from step 4.
This delightful loop relies on Mighty Mutanimals acting as the ultimate engine, leveraging its entry trigger to plant the initial seed while its alliance ability connects the dots. Whenever a new body arrives—starting with the 2/2 red Mutant token—the alliance trigger feeds a +1/+1 counter directly onto Herd Baloth. That influx of power immediately awakens Herd Baloth's own reflexive trigger to churn out a 4/4 green Beast token, which in turn loops right back into Mighty Mutanimals' alliance ability to repeat the cycle indefinitely.
