Like Guild Deception can be really strong, someone a while back joined the game and got to Mythic right away with a deck that was $4-8. It plays like a toolbox and can be pretty effective. Not S tier, but still pretty good.

Mill Deception with all the sleeps is extremely dangerous and difficult to counter if you don't have relic removal and they draw well. The overall win rates are not fantastic, but they seem to have a niche in the current meta.
