Sorry if this is the wrong place
Hello! While I believe that we should ban Comatose in singles, in BH Doubles it would be better, in my opinion, to restrict it to one user per team. Here's why:
There's a strategy I can see becoming prevalent in Doubles, although it's terrible in Singles: Sleep Talk + Comatose + Trick Room. The thing here is that Trick Room setters need to be wary of broken stuff like Aerilate Rayquaza Boomburst, but with Comatose and Psychic Terrain support, they can get Trick Room off at Priority 0. This is actually huge. The only downside is that you can't run any other moves but you could always run some move on your other mon that hits it (think EQ).
I say one user per team (not two) because otherwise people can run ComaPhaze just like in singles, except there's a 50/50 chance whether Sleep Talk is going to hit the same opponent twice or each opponent once (or whether it hits a more passive mon like Registeel). With one user, running ComaPhaze in Doubles is basically impossible.
