Esika's Chariot + Agatha's Soul Cauldron + Kirol, Attentive First-Year + Metallic Mimic

Esika's Chariot

Agatha's Soul Cauldron

Kirol, Attentive First-Year

Metallic Mimic

How it works

1. Cast Esika's Chariot by paying 3.
2. When Esika's Chariot enters, it triggers.
3. Holding priority, activate a creature you control that has a +1/+1 counter on it using Kirol's ability by tapping two creatures you control, copying Esika's Chariot's trigger.
4. Resolve the copy of Esika's Chariot's trigger, creating two 2/2 Cat creature tokens, which each enter with a +1/+1 counter on them due to Metallic Mimic.
5. Repeat from step 3, using one of the Cats to activate Kirol's ability, and then tapping both Cats.
