I keep getting tagged and stuff about Charizardite Y but I haven't changed my mind, Charizardite Y isn't worth a ban and should not be banned. However, I've thought about the issue and the state of the metagame more and I've come into the conclusion that both Charizard Mega X and Mew should be banned. I also wouldn't mind an outright ban on both Charizards as a whole.
I still don't understand what's the fuss about Charizardite Y, it ability to flinch with an Air Slash and the fact that Rock Tomb isn't really something concrete and that's all people like to highlight when talking about that Pokemon. Flinch and miss chances are a part of the game, and many Pokemon can hax through their usual checks. Charizardite Y has a glarring typing weakness and it's a one-trick-pony, honestly, I have never been afraid of that Pokemon in the builder. However, Charizard-X is the behemoth that people need to give extra respect in the builder and in-game. Its typing is amazing and so much different than regular charizard typing which makes a lot of Pokemon be forced into mega evo guess ontop of which mega zard it is. It has a fantastic movepool that is actually abusable, it can be max atk offensive, def offensive, spdf offensive, it can even run max def counter, and has a lot of variations in moves; bdrum, sd, flame charge, counter, eq, brick break.. which allows it to pick what it wants to check. Its moveset being undiscernible at preview makes it even more broken than Y.
I do agree Zard X has more opportunity cost, and one of the reasons I don't think/didn't think both zard should be restricted/banned is because they have a lot of common checks that are actually being well integrated in the meta - TTar, Mega Gyarados (can lose to impish wisp zard x not y l0l!!), diancie, malt, garchomp, lati@s, heatran, greninja... are all on the safe side of checks. As long as you don't repeat the same check, zards will have a problem teching them. But what I found actually annoying in current meta ORAS isn't Zard as a whole but Zard with the other popular threats in the meta that can rend these checks actually useless - mentioning here manaphy, mew, maw, gard... so as a whole the meta revolving around zard is pretty unhealthy.
Banning Charizardite X is actually the logical answer honestly as it is the most restricting Pokemon between the two forms. Rocks are afraid to click moves due to counter, physical mons are afraid to be sent in due to wisp, and blitz+outrage are 100% accurate, and it forces many guess in-game and on preview. Charizardite Y ban is such a mickey option as the mon doesn't really have that IT factor, it's probably one of the easier mon to check. That is the logical thing to do. But imo, looking more in the future - I do believe that both Charizard should be banned at the same time. Banning X or Y alone isn't really changing anything in the meta. Banning X still means zard y + mana/mew/gard/steels... terrorize the meta and is annoying to check or play around. Banning Y alone means that nothing is fixed - X is still King and can bend itself as it wishes - it can beat dos ttar, can counter the terrakion and dnite, can burn the sawk, can sd on the chansey etc... My final opinion is that we should ban both zards.
b-b-b-buuuut deggg! Mah manaphy and victini broken!!!! That's just speculation and it's uncalled for but imo I can delve you more into MY speculation. Bold prediction - Manaphy will not be broken, Victini might not be broken but it depends on how Vic+Mana meta plays. Vic can check many mons and can also adapt freely but I believe it will still have lot of counters like bro, mana, lati@s, ttar, diancie and some others I prob forgot. Without Zard, Manaphy check are more free - gard, sylveon, hoopa, meloetta, pz (i think its a 5050), magnezone, serperior, new electric entrants should keep it at bay. The only thing I'm afraid of is Mana+Vic cores sending us to the same meta that zard shaped but if that's the case - Victini would be the culprit.
Also when Zard leaves, Mew also has to go. It's kinda insane now even w/ zard, the stall set alone can deal with a bunch of offensive mons but when u throw in offensive mew, scarf, band, and more it becomes a pain to deal w/ - like ttar, sect, gard aren't "checks" anymore.
The road to save ORAS is clear - Ban Charizardite X, Y and Mew, then monitor Victini.
