I will say this now but Landorus kicks insane amounts of ass~~
Swords Dance boosted Life Orb Explosion does a 97% minimum to max /max + Groudon, meaning that with just Stealth Rock it's a 100% chance at an OHKO. + 2 Stone Edge does like 79-90% to sp.def Skarmory, this thing is just so baddical.
Victini's cool as a Scarfer for sun teams having trouble with Mewtwo, its Trick Room set is kinda shitty. Haven't tried Final Gambit but I can't imagine it'd be that good.
I'll get back to you on Kyurem but I'm not expecting much.
