Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Well, I wouldn't advice joining till at least they figure out what the hell they are doing. They are testing to see if Shaymin-S and K-W and Genesect are not broken in the monotype meta-game.
And Fairy isn't a bad type, its just hard to use. if you want mind numbing, just go psychic and use stall breaker mew + Mega Medicham like most ladder guys do xD
Well then you factor in it can even abuse a Sub-Seed set to fuck over its usual checks (unless its Scarf Mamo with Icicle Spear) its sorta good game there.
Ice is unusable, but Grass can be quite a force is you bother to build it right (I'd much rather just wait for Mega Sceptile tho so you can have some kind of reliable offensive presence tho)
