@ lavos Spawn : hey, thanks for the rate and the very nice analysis. I know CB terrakion is one of the biggest threat of the team with volcarona. I have to wast stone edge with latias or hope for a miss to kill him. Scizor@bullet punch is the only great way to handle it, it's why conkeldurr could work pretty well. But if don't have volcarona, I lose an argument against sun teams and I get weak to sandstorm stalls with gliscor :x If I put conkeldurr, I have to take another pokemon to beat stall teams. Anyway, I think Mamoswine is the best way to lure Terrakion and Volcarona.
Thank you again lavos Spawn for the rate, I considered all the changes you suggested ! ^_^
