Hey celever, welcome back! I'm on the road and I don't like making short posts in viability rankings, so I'll keep this short: Mismagius is really weak. It really doesn't have the bulk to set up, as 65/65 physical bulk means any physical attack will severely cripple you; 65/105 is okay but still not great. It's still a good Pokemon, hence its B+ rating, but I'm really against a move to A-.
