Hey, guys. I just got into the competitive scene with this gen but I'm still something of a Karenfag. My team consists of a Haxorus, Ferrothorn and a Gourgeist - predictably, it tends to get dunked by Fire-types. I've been considering adding something to stop the flaming onslaught, but none of the water-types appeal to me. So I was considering Volcarona, (Mega-)Aerodactyl and/or (Mega) Mawile. Perhaps not the most Smogon of choices but they're all anti-fires that I like.

What do you think of these 3, or do you have any other suggestions? I'd be using them straight off of Smogon and then tweaking them to my liking.
