Cant wait to hear peoples thoughts!

Go to relic castle, get earthquake, Garchomp will die with Dig.

Just wondering: what tier is this team supposed to be? Garchomp is Uber, which would automatically place your team in Uber, but you don't have any other Ubers on your team... Meanwhile, you have NU pokemon like Zangoose there, too.

Hrm, a Zoroark with Dig? First of all, Zoroark have base 60 Defense and Special Defense, so basically Earthquake is your death. And Hone Claws raises Attack, so you should invest in Attack, not Sp. Attack. And for Froslass, I would recomend Ice Beam over Blizzard. It's the same case as Thunder and Thunderbolt; you get a little less power, but more accuracy.

Dig is just a horrible move, period. The moment you Dig down, your opponent will either Earthquake you to death (Earthquake has more base damage anyhow) or swap to something that flies/Levitates, so your Dig ends up missing and your opponent gets a free switch. Swap all Dig for Earthquake.

Dragon Rush has horrible accuracy. Switch it for Dragon Pulse. That is another key to victory. And why do you give Zangoose Rest without a Chesto Berry or Sleep Talk? That means Lucario can 2HKO you once you Rest.

ok people i want u all to stop posting on this. my dsi was stolen with pokemon white in it so...
