Allright /vp/ I just beat Diantha, this was my team:

>Blaziken, the one I got with the mystery gift code. lvl. 73. Sky Uppercut, flamethrower, bulk up and blaze kick. Used him to beat the crap out of Wikstrom, also with 3/6 pokemon from Diantha's team.

>Golurk, lvl. 64. Helped me with half of Malva's team. Knows shadow ball, earthquake, shadow punch and stone edge.

>Florges, I wasn't so sure about catching Flabébé but I don't regret it at all, took down by herself Drasna's team, except for Dragalge, Golurk took that one down. Lvl 69, knows Moonblast, dazzling gleam, energy ball and wish.

>Venusaur, main pokemon for the battle against siebold, it was hard to beat that damn Gyarados but Venusar made it possible. Lvl. 62, knows frenzy plant, venoshock, sludge bomb and petal blizzard.

>Lucario, the reason I took Lucario was because of his megaevolution, but I think it's not so good as a pokemon, it sure took me through the 8th gym, but was worthless in the Elite Four challenge and the Champion battle. Lvl. 61, knows close combat, swords dance, heal pulse and aura sphere.

>Greninja, so this was my last pokemon in the battle against Diantha's mega-Gardevoir, it had like 33Hp left and gardevoir was still a in yellow HP. Greninja was only at level 63 with dark pulse, extrasensory, scald and surf. Not only was my only pokemon left, but also the only one that could outspeed megaGardevoir.
Finally I chose to attack with Scald, it lands a critical hit, doesn't kill the damn thing but burns it, megaGardevoir misses it's moon blast and gets killed by the burn. Best finale ever!

What team did you use for the Championship Battle?
