M-Mawile is perhaps one of the most mindless pokemon to use in the tier. It is so easy to slap on a team and win that it's down right awful. It makes players like myself rack up easy wins and makes the team building process irrelevant because mons like M-Mawile basically screams "Free ELO" or in most cases "Free Wins". Oh I need something to pressure offense? M-Mawile. Oh I need to break stall? M-Mawile. Oh I need something that can effectively handle every legitimate archetype in the tier...go ahead take a guess. I'm not even exaggerating these points either.
The worst part about M-Mawile is not how effective it is from a 1v1 standpoint, the scary thing is how it can make an already great team build become extremely potent, with just one single mon. It puts pressure starting from the team preview down to that one turn where both of you know it's gg because Mawile just came in and set up with SD or because the Sub set just screwed over your entire team. I believe Mawile is just broken simply for being broken. It's not necessarily over centralizing cause in reality you can prepare for M-Mawile all you want and still lose. Yeah that Defensive Arcanine (lol Arcanine in OU) isn't beating Sub sets especially with the team backing it up, A for effort though.
Also I'd like to touch upon at the very least two sets from M-Mawile that are quite popular. I don't have experience using it in TR (although I got wrecked 3 times on a suspect ladder by knock off TR mawile by MikeDawg if you want to call that experience rofl) but I've used both the SD and Substitute sets on various teams with great success on both.
Sword Dance set is basically the ultimate win condition on M-Mawile. It doubles its already effective 678 attack to such an extreme level that the term "Wall" becomes irrelevant. This on top of the fact that M-Mawile has access to Sucker Punch allows it to pressure offense into pure mind games or simply downright lose to M-Mawile at times. Oh yeah going to note since people keep bringing this up as an argument, how many things actually resist Sucker Punch? From a typing perspective only Dark, Fighting, and Fairy can actually do this. Every other single type is at the very least effected by a neutral priority move coming from either a 678 attack stat or twice that if SD is up. With this being said the access to such priority mitigates the Speed Factor of M-Mawile tremendously and in some cases won't even have to worry about its slow speed because of Sucker Punch. SD pretty much just man handles stall after its main stall checks are out of the way such as Char X, Victini, Counter Skarmory (Not even that good of a check honestly), etc.
Subpunch or Sub sets in general is what I believe makes M-Mawile hit the threshold of broken. With a single substitute, M-Mawile mitigates so many of its flaws that it originally had. Behind a substitute M-Mawile doesn't have to be over dependent on sucker punch as the Substitute gives it a free turn basically at the cost of 25% which is a minuscule problem for M-Mawile if Sub is all you need to dismantle the team. Being behind a substitute allows it to not worry about any status effects what so ever so there goes your bright idea of burning it. Phasing M-Mawile out comes at a price now as phasing moves such as Roar and Whirlwind fall under the priority bracket where they would go after you are hit with a 150 BP Focus Punch by a 678 attack stat to boot.
Ok let's try a scenario that I've done so many times behind a sub with ease that demonstrates how mindless and easy it is to use. I bring out M-Mawile, and I bring it out early. I do this on purpose to lure out the main checks to the SD set or just to lure a problem with my team that is susceptible to M-Mawile (I mean everything pretty much is). They switch into Heatran or something like that and they come to find out its a Substitute set. Now the player has one of two choices, they can either have Heatran take the Focus Punch and lose, and the best Heatran can do is remove the sub with a fire move. Or two, they can have the bright idea of switching out Heatran and have something take the brunt of a hit from M-Mawile and act like that shit didn't hurt like hell, oh and the substitute is still there lol. Best part about this scenario is my Healing Wish Latias in the back so we can do this all over again :) and proceed to have M-Mawile be the sole factor in a loss that should've been mine if I didn't abuse such an overpowered mon.
Also can someone please tell me the real logic in why we're saying stuff along the lines of "Oh Char X and M-Pinsir beat it, so it's not op" o_0. I need some good logic with this cause you just used two things that are already suuuuuper strong and can handle a lot on their own in the tier. Using pokemon of their high caliber doesn't prove that M-Mawile is not broken what so ever. So if you have a good argument regarding this, please let me know I would love to be entertained with this idea.
"It's easy to play around once you know its set" Lol no it isn't cause now you're forced into total mind games and hoping that you aren't switching into things like neutral Play Roughs, Iron Head, Focus Punch etc. Yeah people call it 50/50 but I always thought that was a BS argument so I'm not going to elaborate further than that. Also knowing a mons sets will always be a factor in easing pressure mid late game as you know what needs to be done to check the mon. The difference with M-Mawile is that it doesn't have a single care in the world cause in most cases it's backed up by teammates to help with any minor flaws, and most of the time it's built as a stand alone mon as well so it's not dependent on those teammates if and when that time comes.
"I never had problems with M-Mawile" I never had problems with Aegislash with just running one check to it and look how that turned out in the end in terms of its tiering. Your sole experience against a certain mon is not necessarily a factor in stating how a mon isn't broken. Also yeah if your team is something like Rotom-W, Talonflame, Lando-T, M-Pinsir or basically teams with a bunch of M-Mawile checks, obviously you're not going to have too many issues with M-Mawile.
