lol the unanimous choir of people claiming it's broken kinda seals this thing's fate.
To be fair, MMence can actually be defeated. Offense can deal enough chip damage to it while it tries to set up to revenge kill it with an Ice Shard user. More balanced and defensive teams can run something like Skarmory, Zapdos, Cresselia, P2, etc... But the thing is, the amount of preparation required to beat MMence is completely overwhelming. If there's anything that shows how much MMence bends the tier in half, it's the fact that teams are running Banded Weavile, Scarf Greninja, 168 SpA or something Rotom-W and HP Ice/Ice Punch on literally everything. People are prepared for this thing, they have absolutely adapted to it. And it's still way to much for people to handle.
On the ladder, Sub DD Mence is the most common Mence set by far and I'm pretty sure you can do alright in ORAS by just running Taunt Counter Skarm as your Mence counter as a result. But while that set is certainly very good, I feel like people are kinda wasting Mence's potential by sticking to it, because so many of its would-be counters just get ruined by a random coverage move You can run Fire Blast to lure Skarm, you can run Draco Meteor for Zapdos/Rotom-W/Rhyperior, you can run Hyper Voice for Slowbro, etc. If you think MMence is scary now, imagine what it would be like if people got creative with the sets, and you'd have no idea if your Air Baloon HP Ice Hetaran will end up on the receiving end of a Hydro Pump. Personally, my favorite MMence set is DD/Return/Fire Blast/Draco Meteor. Fire Blast+Draco smashes like, half of Mence's switchins, and once said switchins are gone you can then sweep with DD+Return which is really all you need at the end of the day. Also, when people see DD they always think Skarm or Rotom-W can easily switch into it, unfortunately that is not the case. If anything people are not abusing MMence enough imo, if it seems underwhelming to anyone for any reason it's because people just spam that one set which quite frankly is becoming predictable and boring.
There is literally no downside to using MMence, it is amazing against every playstyle. I think it's kinda telling that a Pokemon that is, thanks to its ability to go mixed, a better wallbreaker than MPinsir (who was one of the best wallbreakers in the tier), is actually worse vs Stall than any other playstyle. Oh sure, Stall hates it, especially the mixed set. But at least Stall has switchins. Usually, offense considers itself well covered against something if it can't switch into something on your team more times than you can send something else in on it return. For MMence this is simply impossible. You cannot make a competent offensive OU team atm without at least having 1 or 2 Pokemon which give MMence a free switchin. And what switchins does offense have for MMence? Thundurus? Anything else is screwed if it DDs on the switch which it does very, very easily. MMence is ridiculously good vs offense, it may even be better in that matchup than Greninja (a Pokemon that harasses offense so hard it's almost guaranteed to be next in like for suspect) since it has effectively the same speed tier, FAR more bulk, recovery, and relies less on prediction. I mean yeah I guess it's slow pre-mega but thanks to Intimidate and its resistances it Megas so easily even vs offense it's a joke. It's also amazing vs balance because it can just continuously wear down its checks, and tank like 90% of hits any balanced team can muster thanks to its ridiculous bulk which, need I remind you, is higher than that of Ferrothorn Skarmory and Slowbro, and on par with that of Tangrowth and Hippowdon. Because yeah, MMence isn't just the single best offensive Pokemon in the tier, it's one of the best defensive ones too.
Right now there is little to no reason to run a mega that isn't either MMence or MSableye, since any advantage or team synergy another mega could bring is completely trumped by MMence's ability to do whatever the hell it wants. With MMence you can literally just completely forgo defensive synergy, MMence+4 trappers is a thing that actually exists and it works. This thing singlehandedly causes ORAS OU, which should normally be a really solid tier, to be a absolute farce which no sane man would indulge in. Please quickban this, I don't want us to waste any more time, we have way more interesting discussions to have regarding the brokeness of Greninja and maybe a couple of ORAS megas too, (though right now it's hard to see which ones are potentally broken behind all of the MMence) and I would like to start those as soon as possible.
