Yo
So I've been trying a bunch of different stuff with a bunch of different mons lately. And a couple of things stand out as kinda too powerful or just stupid.
1: This lil' shit.
I never really quite understood why it was untanned in the first place.
Does it have counters? No.
Does it lose to offense like most wallbreakers? No.
Is running it on your team ever a bad choice? No.
Is it insanely stupid fast to the point where even modest variants outspeed latios? Yes.
Really, the ONLY arguments ppl have pushed forward for this thing not being completely stupid broken is "oh but, motherlove, gal wing checks it"
Gale wing checks 90% of offensive mons regardless. It's also predictable as fuck and easy as hell to wall. Gale wing checking it isn't a good argument. You know what else was checked by gale wing or like pixilate espeed? Mamoswine, Terrakion, Keldeo and Hoopa unbound.
I have yet to try a skymin set that isn't really good (not your average good, like actually really good). I've gone through tinted, adapt, poison heal (subseed), no guard, mixed refrigerate, gale wing even serene grace. It's just so fast and powerful.
(Tbh I think most ubers that dropped down like genesect or deoxys speed are broken but they can wait)
Unfortunately replays were broken for some time so I didn't get to save many, but just build a team, toss a skymin in it and win games, it's ridiculous.
Moving on (there's some debate rising around this one), illusion. It's been under the radar for a while since nobody uses it, but I've been spamming it on teams like crazy lately and it's really the easiest way to win games.
To make it simple, there is so many good options and it's completely impossible to predict. A good example is rotom-c (the grass one). It can OHKO suicune and skarmory 2 of the most frequently used and metagame defining pokemons in AAA and they're also really, really easy to lure out. Send in your entei, opp switches in on suicune / hippo / cancerzu / ff doublade / ff skarmory / PhisDef manaphy but NO it was a ruse and boom their pokemon is gone, it's as easy as that. And the thing is you can do that multiple times through the match. Sometimes like kill 2 pokemons and trick a choice specs to chansey before dying. And after this there's probably at least a couple of mons on your team that can win easily. And you can literally run whatever you run depending on what you want to kill. You want to ohko skarmory and chansey, run lucario. You want to create a free win for your latios, run darmanitan. It's literally so easy.
Anyway, again, replays were down so I guess this garbage will have to do:

Unfortunately I had some pretty good battles like getting a clutch ohko with illusion breloom on heatran and sweeping with gale moltres or removing the opponents' vaporeon to win. But I can't show them because I downloaded them and don't know how to share them..
