Hi! Not a Mamo set, but its decent.
Garchomp - Bulky support set with enough speed to outspeed timid Kartana and you can OHKO it with flamethrower. It gives you the edge over Ferro as well, however SpDef Ferro takes around 40%, which is not that good.
AshGren - Standard. Hits hard.
MiMiQ - Get out of the jail free card since this team is kinda weak against rain.
