TAHAHAHA!! Yep, that's almost how I whooped his ass in the super singles, except instead of Garchomp I used a Choice Band Dragonite on my team alongside Ferrothorn and Chandelure.

I needed no legendaries or psuedo-legendaries!
My Arcanine and Swampert were more than enough!
(half the time)

I had my trusty Mienshao with me through the many battles I had at the Subway. It made for a killer lead.

Fuckin' overpowered dragon shit. I feel your pain, Ingo.
