Arcanis the Omnipotent + Tolarian Kraken + Ley Weaver

Arcanis the Omnipotent

Tolarian Kraken

Ley Weaver

How it works

1. Activate Ley Weaver by tapping it, untapping two mana-producing lands.
2. Activate the lands by tapping them, adding at least 2.
3. Activate Arcanis's first ability by tapping it, causing you to draw three cards.
4. Tolarian Kraken triggers three times. Resolve the first two triggers, causing you to pay 2 to untap Arcanis and Ley Weaver.
5. Resolve the last Tolarian Kraken trigger, choosing not to pay.
6. Repeat.
