Movepool Changes - Stealth Rock, Stone Axe, Stone Edge
Competitive Corner - Mega Haxorus has plenty of options to make use of with Technician! Breaking Swipe is a drawbackless 90 BP Dragon-type STAB, Dual Chop reaches a whopping 120 BP, although it does come with a 10% chance to miss, but scarier still is Scale Shot's average of 112.5 BP along with a speed boost, provided you hit. In terms of secondary STAB, Haxorus has Rock Tomb as its disposal for yet another form of speed control, coming together on a 90BP 95Acc move, or risking Stone Edge is always an option, as is Stone Axe depending on how that move works on a non-Legends Arceus environment. The speed lowering motif continutes with Bulldoze being a reasonable 90BP option, alongside Earthquake being the slightly stronger option, as coverage to get past the Steel-types that resist this unique STAB combo. That said, hopefully Mega Haxorus is a bit balanced by it's dropoff in Speed, to make Scale Shot sweeps a bit less attainable, with it being outspeedable by anything faster than Jolly Talonflame at +1. The main problem with it though, is that since its speed boost comes alongside a strong STAB attack, it could be tricky to limit it to just one speed boost, however, unlike Dragon Dance, its Attack stat does stay the same, so it effectively needs both a Swords Dance and two Scale Shots to sweep all that easily, or to have a teammate either weaken the opposing walls, or take down the opposing scarfer / revenge killer before trying to go for a sweep, which is hopefully enough to balance this monstrosity! The relatively low Special Defense and the newly added Rock-type weaknesses should hopefully also make setting up a bit trickier.
Flavor Corner - Haxorus is very clearly based on dinosaur, extending the concept of some species having long tusks into whole ass battle axes. I decided to take this step further and tie in with the common media trope of dinosaurs coexisting with prehistoric humans, and fleshing out the axe inspiration. Mega Haxorus gets two whole stone-made axes protruding from their mouth, as if it were a caveperson just honing them à la what humans did in the stone age. This should explain Technician! As of writing this I saw another user already came up with a really cool submission with Technician also, but hopefully mine can contrast itself from theirs with the new type and the flavor justification for repeating the ability.
Mega Mienshao

Movepool Changes - Avalanche, Cicle Throw
Competitive Corner - Mega Mienshao has a few options to make use of its ability: Focus Punch remains the most impressive, being able to land a ridiculous 225 BP-equivalent move should Mienshao be able to use the move without being hit first. Revenge's ceiling is now 90BP and could be an interesting mixup if run alongside Focus Punch, as if the user does damage Mienshao to avoid it using Focus Punch or setting up a Substitute, it gets hit with 120 BP worth of Fighting-type damage, same goes with Avalanche as coverage. Cicle Throw also shares the same 90BP if the user is able to use it without being hit, and it also forces out the opponent, which is especially useful if the opponent switches out, although, you'd have to have a very good reason to do so against this monster. And finally, Vital Throw seems like the most middle of the road option, not offering anything very unique, bar a 105 BP hit if the user isn't hit beforehand. Mienshao also has many other Fighting-type moves with very high base power and normal priority, such as Close Combat and High Jump Kick to use, which are probably better than all of the aforementioned decreased-priority Fighting-type moves bar Focus Punch itself, of course. Substitute is extremely important for Mega Mienshao to be able to get in a good position to Focus Punch, which shouldn't be too detrimental considering it has Regenerator pre-Mega Evolution, and U-turn should also help gain momentum as Mega Mienshao will very consistently force whatever's in front of it to stay in and attack. However, and sadly, for Mega Mienshao, it does struggle a bit with having all moves it might want to run in one moveset, Substitute and Focus Punch are very important for it to set itself apart from a regular Mienshao with a Life-Orb, and it wants coverage for Ghost-types, a non-decreased priority Fighting-type move, and likely U-turn in there too, to be the best it can, but it has to give up on one of these.
Flavor Corner - Mienshao seems to have a very broad inspiration in terms of martial arts, yet "qi" is a very important concept for a lot of them, so I thought doing something related to it felt reasonable! A "Focus Punch"-esque ability then came to mind, and I knew I had to make it! But I think it works very nicely for Mienshao all things considered! I wanted to draw more conceptually from this, but I couldn't get much more than martial arts ermine, so hopefully this ability is a reasonable realization of this mon!
