Question

Would magic coat backfire taunt?

Answer 1

Generation lll-lV
Magic Coat reflects any move that inflicts status conditions back at that move's user. For example, Leech Seed, Attract, or Thunder Wave will reflect back to the target. Teeter Dance and Memento are unaffected by Magic Coat.
Generation V
In this generation, Magic Coat can reflect Teeter Dance. Magic Coat can also reflect entry hazards and moves like Taunt and Torment. Magic Coat reflects the same moves that Magic Bounce does.

Yes, Magic Coat would backfire Taunt
