And your "humble" opinion has good reason, no?
This team has no physical attackers ... And Infernape isn't very useful as a bander without insane prediction skills. I'm doubting Infernape would help this team at all, aside from wall breaking. Even then, certain walls like Cresselia (lol duh) still wall Infernape, and no, unless you're facing an idiot Spiritomb won't be KOing Cress' with Sucker Punch.
My point is, without a physical attacker, you're pretty much doomed to be walled by Blissey forever. With Infernape, you're probably going to be forced to switch him in early game, and end up losing him too soon to be helpful. I don't think 'Ape is going to be helping this team too much, whether he'll be a bander or a wall breaker.
