Hey, this is Dece1t, aka Stun, here to do a kinda slap-dash RMT with the Ice Team I used to peak as the finalist for ice in LTLC 2. To be honest, I was a bit disappointed. At first I was doing well on the ladder, and I was happy with my progress, but as soon as I hit around 1400-1500, the game just abused the living shit out of me. I was haxed pretty bad, and that ruined my GXE, and my chances of my original hopes to do better than the previous time I won. Funny enough, this is my Nuke 'Em team, but I just replaced Piloswine for Mamoswine to ease up the Steel matchup a bit, as well as have a bit more firepower on the team. Anywho, here's the team:

As a little side note, Ice is one of the hardest types to play with. It's very hard to ladder with it successfully, especially with Steel and Fighting being 2 of the most used types atm. Hope you enjoy the team though, regardless.
