Jorn, God of Winter // Kaldring, the Rimestaff

Rimefeather Owl

Lithoform Engine

How it works

1. Activate Rimefeather Owl by paying 1S, putting an ice counter on Lithoform Engine, causing Lithoform Engine to become a snow permanent.
2. Move to your combat phase, and declare Jorn as an attacker, triggering its ability.
3. Holding priority, activate all mana producing snow permanents you control by tapping them, adding at least 3.
4. Activate Lithoform Engine's first ability by paying 2 and tapping it, copying Jorn's triggered ability.
5. Resolve the copy of Jorn's ability, untapping all snow permanents you control.
6. Repeat from step 3.
