I WON!!!!
For anyone thinking how, i used mewstics "Misty Terrain" to change the terrain and used my greninja with water moves 2 take out most of his team, his excadril fell to my Medicham who had a Focus Band since excadrill can 1 shot everything. other then that i used Sylveon to beat Torterra(they both died). Took me a couple of tries becouse of focus band but i won.
