hopefully this isn't against the rules as a one-liner of sorts, but i was curious as to how the meta shifted (since ORAS, which i realize isn't particularly relevant but it's the closest thing i have to relate to) so severely that alakazam isn't even considered viable anymore. is the surge of the greninja forms crippling its usefulness - as well as how common mega scizor is? not saying it should be on here (hard to say that since i don't play SM OU really); was just wondering why it's considered below the likes of decidueye and talonflame now.
This generation, alakazam really misses the speed tier Mega Alakazam possesses. That outspeeds tapu koko, greninj, its ash forme, weavile(less relevant but still there), neutral pheromosa, etc.
So that this isn't a useless post I'd like to talk about a couple of nominations.
Charizard-Mega-X --> B+/B
Strongly agree. Mega Charizard X is not that great anymore, facing competition with Volcarona as an offensive fire, and is revenge killed by Scarf garchomp and niheligo even at full, and gengar, pheromosa, and keldeo require little chip damage, and it is super easy to chip Zard. Scarfers, however, are not close to Dragon Dance's only major flaw. Pokemon like Tapu Fini and Landorus-t can check they are healthy. Dugtrio massively annoys it, allowing it to do little damage against stall. It is super hard to get a DD against offensive builds.
Charizard-Mega-Y---> A
Undecided, leaning towards disagree. Charizard-Mega-Y is insanely strong with sun boosted fire blasts. Focus Blast and Solar Beam hit few things that resist fire. Roost allows you to heal up. Dugtrio traps many of its checks. This thing can come in on many mons like Scizor-Mega, Celesteela, Venusaur-Mega, Sableye-Mega, Ferrothorn etc. It can then proceed to blow back a mon.
Looks all good and solid, until you realize that it isnt as good in reality as it seems on paper. Looking into the playstyle by playstyle matchup will allow us to better understand.
Stall-> Okay Matchup, leaning towards bad, but beats some stall teams, and can pressure others.
Chansey walls this thing. Obviously, thats why you have dugtrio to trap it. Problem Solved! Not really. Dugtrio cannot trap both chansey and toxapex in the same game. It has to pick one. The obvious choice is chansey. Zard Y still has a very hard time breaking Toxapex. Teams possessing only one of these two will have a much harder game.
Balance-> Okay Matchup, leaning towards bad. It can beat many balance teams by annoying them with Sun boosted fire blasts. However, toxapex, mantine, sub coil zygarde, nihelego massively annoy you. You have to weaken zygarde and niheligo severely, with switching in multiple times. You also get pressured by rocks. Other balances, although rare, can also pressure this with rocks.
Bulky Offense--> Good Matchup. There is nothing really besides zygarde, niheligo, or garchomp that really wants to switch in. These mons aren't that common on BOes. It can still pressure with rocks.
Offense--> Okay matchup. You can come in on pokes like Ferrothorn, an unboosted steela, magearna, choice locked keld etc. and threaten them out. However, scarfers like garchomp and keldeo, however no t very reliable can switch in at least once, and pressuring zard with rocks + limited switchins helps. Niheligo and Sitrus Zygarde on offense are a really poor matchup. DD zygarde, volcanion, and even greninja can take a fire blast.
Hyper Offense-->> Poor Matchup
You barely can come in on nothing but free switches after a mon has died. Even then, there are still few mons that you can come in on after a mon has died. Some are QD non Normalium Z Pheromosa, Choice locked chomp, choice locked keld, and Mega Mawile. It is also not hard to RK on an HO. Some other mega like Mega Metagross, Mega Mawile, and even Mega Scizor and Mega Sharpedo would annoy hyper offenses far more.
