Hylda of the Icy Crown + Glare of Subdual + Ashnod's Altar

Hylda of the Icy Crown

Glare of Subdual

Ashnod's Altar

How it works

1. Activate Glare of Subdual by tapping an untapped creature you control, tapping a creature an opponent controls.
2. Hylda of the Icy Crown triggers, holding priority, activate Ashnod's Altar by sacrificing the creature tapped in step 1, adding CC.
3. Resolve the Hylda of the Icy Crown trigger, causing you to pay 1 to create a 4/4 Elemental creature token.
4. Repeat.
5. You may also repeat this loop during each turn.

This clever engine turns your opponent's own board into the fuel for an escalating army, all coordinated by Hylda of the Icy Crown. By utilizing Glare of Subdual, you can tap down an opponent's creature while simultaneously sacrificing your own tapped asset to Ashnod's Altar for mana before Hylda's triggered ability even resolves. That very mana pays for Hylda's ability to generate a fresh 4/4 Elemental token, which immediately steps in to keep the loop going.
