Wait, so you're saying that Hidden Strike:
• Works like Download, basin off of the enemy's lower defenses
• Changes type to hit the strongest weakness, basically making it always do ATLEAST 2x damage since every Pokemon has a weakness if ignoring Abilities
• Gains STAB, no matter what
• Breaks through Protect, Substitute, and other moves similar
• Has 100% Accuracy and 90 Base Power.
• Benefits from Priority from Ninjutsu

Forgive me if I say thats pretty FREAKING BROKEN, especially with the base 125 Attacking stats. AG would be holding two Pokemon if such an attack existed.

Anything that could counter Mega Greninja w/out that Move would be neutered the moment he used it.

Edit: I digress, this is an RP, not a competitive game XD If the GM's okay with it, I will as well
