Arcanis the Omnipotent + Tolarian Kraken + Ilysian Caryatid

Arcanis the Omnipotent

Tolarian Kraken

Ilysian Caryatid

How it works

1. Activate Ilysian Caryatid by tapping it, adding 2.
2. Activate Arcanis's first ability by tapping it, causing you to draw three cards.
3. Tolarian Kraken triggers three times. Resolve the first two triggers, causing you to pay 2 to untap Arcanis and Ilysian Caryatid.
4. Resolve the last Tolarian Kraken trigger, choosing not to pay.
5. Repeat.
