Mega Evolution & Other Gen 6 Crap.

[NICKtendo DS]

There appears to be a button in the battle interface that triggers Mega Evolution when possible.
Though from what I understand Mega Evolution doesn't cost a turn, the fact that it has to be activated manually, there has to be some sort of limits to it. As a matter of fact, why does the process need a tutorial if it were a simple "hold and it'll evolve" process (contradicting what I said earlier).
It is also stated that the game just gives you a Mewtwo with its Mega Stone for the tutorial. I hope it's just temporary and not that the game just gives you a Mewtwo for free, because that mofo needs to be earned!
