Ooh finally:
6 move + Hackmons
1v1 + Camomons
1v1 + Type Control (unless type control is too new to be nom'd)
6 move hackmons would make Hackmons even more unpredictable, and takes 6 move (an otherwise glorified OU) and hackmons (4MSS rules the world) to make a great meta overall
1v1 + type changing meta is pretty cool, as this introduces an entirely new concept to 1v1, making it have endless amounts of fun.
PH can't be matched with anythinginverse bh y\y
BH can only be matched with 1v1
