What are your best combos to get Master Rank? So far I've managed to get it five times in a row with Mega Garchomp, Chattot, Greninja and Gengar.

Mat Block is such an useful move for setting up sword dance and Nasty Plot, plus EQ and Boom Burst take care of pretty much anything. And if that fails I rely on Chatter's confusion hax to stop serious threats.

I have beeen lucky enough to not come across any pranksters, but it seems that the A.I thinks that throwing at you Veterans and Grandpas maining legendaries is a better idea.
