I played heavy explosion because nothing dies.
Ttar is overrated; it's only good on paper, as the "ultimate" ubers meta-er. But it's not.
Ho-oh burns; that's it's main asset, and it's pretty useful for it. You can technically curse + phaze with it as well, but burning is such a huge asset to stop mew sweeps, lugia, lax sweeps, etc.
I use Mewtwo with curse + selfdestruct since mixing with it is retarded imo. Mewtwo/mew/lugia/hooh all wall mix mewtwos. Self destruct is the only way mewtwo is killing anything.
Mew is pretty versatile, SD + explosion, but I got away with softboiled only because I was partial to it. Mew's the best pokemon in the game.
I played Zapdos with thunder/twave/rest talk.
Snorlax is also pretty standard imo; I used curse + SD once again, and LK. And I used celebi to bell. You pretty much need a beller because of burn/para. I gave it psong + leech seed + recover + hb cause it's stupid to attack with it.
Lugia phazes for me. I made it a curse phazer though; if you skimp out on zapdos, it's kinda unstoppable from there. Hence, Skarm is kinda important.
Skarm plays like standard skarm imo.
Not sure how good raikou is; seems outclassed by zapdos due to lugia and ability to twave.
Cune seems pretty worthless imo; just outclassed by lugia in every way.
