Re: My team needs help
Medicham has a crazy max attack-480 (with the ability taken into consideration). Use strong physical attacks on it, or make it a BPer. It can CM and Bulk Up, so it's rather variable. You need a physical wall. Since I hate skarm, I'll recommend:
EVs: 252 HP, 252 Defense, 6 Attack
~Stealth Rock/Rock Slide
Steelix has many offensive options. Gyro ball, EQ, and exploding are its 3 best, so I'd use those and Stealth rock. The EV spread can be changed to be more offensive rather than defensive...252 HP, 152 Defense, 100 Attack or something like that.
