Hey guys, what is your opinion on running two megas on your team? Obviously you're wasting an item slot, but sometimes I feel that the diversity is nice, I'm mainly talking about just random battles with passerbys.

At the moment I am running Mega-mance, and Char-Y just depending on different situations, If they have a bunch of physical attackers/weaknesss to char, I'll mega it, and keep the Intimidate salamance, or If salamance can do better, I'll use that. I'm just wondering if anyone else runs 2 megas as well, and also, if you do, what two work well together?
