mtg relentless rats commander deck A You Can't Say You Weren't Warned About This is of the C rarity. Vren, the Relentless - Rats

As far as sweepers go, in a Gruul, Izzet, or mono-red deck, this is a great option, but since we're in Mardu, we can be a little pickier with our mass removal spells

As Codsworth's last ability resolves, if the target Aura or Equipment can't legally be attached to the target creature (for example, because the creature has protection from enchantments or protection from artifacts), the target Aura or Equipment won't move

That said, I personally like Nahiri, Forged in Fury for her ability to circumvent commander tax and potentially play a lot of free cards
