There are no held items, but there are still special items like evolution stones. For Simple format though you can use held items if you'd like, but for complex, the focus is all on roleplaying.

I was gonna put a King's Rock on a Charizard and name it King Crimson, then have it summon Jojo stands through the move Beat Up.

No exceptions? 

By the way, it just occurred to me that Charizard has two mega evolutions, so why not allow multiple different custom mega evolutions?
