Jorn, God of Winter // Kaldring, the Rimestaff

Moritte of the Frost

Lithoform Engine

How it works

1. Declare Jorn as an attacker, triggering its ability.
2. Holding priority, activate all mana producing snow permanents you control by tapping them, adding at least 3.
3. Activate Moritte of the Frost's first ability by paying 2 and tapping it, copying Jorn's triggered ability.
4. Resolve the copy of Jorn's ability, untapping all snow permanents you control.
5. Repeat from step 4.
