Seriously? You people must not know how the whitequeen battles
This is a really cool team. But cool doesn't actually mean good!
First off you'd better hope you're 18 or older because Jellicent face fucks your whole team until it suffocates and dies. Unless its user is retarded and allows you a free Pursuit, leaves it in on Dragonite, or gets repeated WoW misses it effectively wipes your team out on its own. Not only is it immune to Endeavor and Rapid Spin (oh god Rocks, they shit on two of your pokes and for all intents and purposes OHKOs another) it also walls every single Pokemon you have by spamming burns.
Also Politoed is a jerk. You have no switch-ins besides Dragonite who falls to an Ice Beam, or two Hydro Pumps with rocks down. Also it switches in on much of your team without trouble.
Volt-Switch is a HUGE problem for you. Closest thing you have for a counter is Dragonite who isn't going to last the whole game. Scizor, Rotom W, Genesect, etc. They all cripple you and aren't directly afraid of Aron.
Specially Defensive Heatran cums spiders all over your team just by spamming Stealth Rocks and Lava Plume. You can't freely Rapid Spin on Heatran and nothing absorbs a burn.
Terrakion is like the honey badger in that it just doesn't give a shit what you do. All it does is Close Combat. With Stealth Rocks down even Dragonite is 2HKOed. You can revenge kill it easily enough and it doesn't get many safe switch ins, so this might not be a big issue.
It should be obvious but if Stealth Rocks are down your team is massacred. Forretress is a good spinner but not a 100% safe one. A lot of SR users like Heatran, Tyranitar, etc could be a huge threat.
Maybe replace Dragonite for an HP Fire Latias. It offers similar resistances, lures in and destroys Scizor Volt-turn, lasts longer than Dnite in sand, beats Terrakion (sort of), stops Politoed, kind of takes on Jellicent (but not really), and probably does more stuff. You do lose CB Extremespeed though, that's pretty important.
Anyway I'm lazy and I know that since I "don't know how good the whitequeen battles" chances are you will blow off my rate by saying you play around all these threats I'm just going to stop typing. Give Latias a try, even though I know you won't.
