Jorn, God of Winter // Kaldring, the Rimestaff

Rimefeather Owl

Strionic Resonator

How it works

1. Activate Rimefeather Owl by paying 1S, putting an ice counter on Strionic Resonator, causing Strionic Resonator 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 Strionic Resonator 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.
