Agatha's Soul Cauldron + Triskelion + Young Wolf

Agatha's Soul Cauldron

Triskelion

Young Wolf

How it works

1. Activate Young Wolf using Triskelion's ability by removing a +1/+1 counter from it.
2. Repeat step 1 until Young Wolf has no +1/+1 counters on it.
3. Resolve all Young Wolf abilities dealing 1 damage to Young Wolf, and any remaining damage to any target(s).
4. Young Wolf dies as a state-based action due to having 0 toughness.
5. Young Wolf's undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
6. Repeat.

This clever loop transforms a humble creature into a lethal artillery piece by feeding its remains to Agatha's Soul Cauldron. By exiling Triskelion into the Cauldron, you grant its activated ability to any creature you control that bears a +1/+1 counter—such as Young Wolf. You can then use that acquired firepower to ping Young Wolf itself, stripping away its counters until state-based actions send it to the graveyard, where its undying ability immediately revives it with a fresh counter to restart the cycle.
