My friend and I are going to battle for the first time in years when ORAS comes out, and I want to drink his tears. I want to make a stall team of non-legendary, preferably weak-looking pokemon for maximum effect. My friend uses damage moves exclusively, but all I know about what his team will be is that it will contain mega Charizard Y. Is this a good start? Other suggestions?
Gliscor w/ stealth rock
klefki w/ spikes
