I'm a spellbooks player. I'd say they're still Tier 1, as they still have the same amount OTK ability, and may still be able to take out Fur Hire. But the meta is currently just swarmed with Silent Spellbooks and Fur Hire right now.
I'm a spellbooks player (no silent magician sadly) and I've playing but without restart my hands are mistly awful. But when i have a good one i win other meta decks.
