Mawile team

[Marcusube]

Mega Mawile works wonders in a Rain Team so you can throw in Politoed, Ludicolo and Thundurus. Trick Room is great too so try using great Trick Room set up Pokemon such as Slowking, Slowbro, Cresselia and Chandelure. Mega Mawile also wants to have a Support Pokemon that shuts down sweepers, mainly on the special attacking side so having fast Physical or Special sweepers is a good idea as well and finally, you may need a Pokemon that stops Status Moves.

Have fun team building and I wish you all the best
