Notes
1. Ulmarus is, technically, multicolored but I sorted him as colorless because that's where MSE has him since he's not an artifact.

Whenever Fury from the Deep attacks or blocks, put a stability counter on it at end of combat.
Fury from the Deep can’t attack or block as long as there’s a stability counter on it.
