I am currently in the final stages of building my ORAS WiFi Singles team, however only one Poké remains to be EV trained: Gible. I plan on using Garchomp as my anti-Talonflame, using him to tank Brave Birds. However, I need to know the minimum amount of EVs necessary for Garchomp to be 2HKOd by BB. This is in case Stone Edge misses the first time, then I can survive a second attack and crush the fire-falcon. Calculate it as if the Talonflame has maximum Attack EVs and IVs, rocks are up on my side, and the foe has a Choice Band. 'Chomp has Rough Skin. Thank you!
And no, he will not be Mega.
