Arcanis the Omnipotent + Tolarian Kraken + Kozilek's Channeler

Arcanis the Omnipotent

Tolarian Kraken

Kozilek's Channeler

How it works

1. Activate Kozilek's Channeler by tapping it, adding CC.
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 Kozilek's Channeler.
4. Resolve the last Tolarian Kraken trigger, choosing not to pay.
5. Repeat.
