I'm worried about Tarsa because of Mylor + Amplify. Taking 3 damage per melee attack is gonna be brutal, and it's gonna be everywhere. I'm mentally downgrading any melee card I see because of how common I think this is gonna be.

I'd also nitpick the word "objectively". Nothing about CL is objective yet. Wavesmith is more expensive than the reward epics and has exactly the same buff. I don't often bring rust to a fight because I don't see armor stacking very often. If it becomes meta, rust will be more important, but ATM, it's no so important.
