Other Metas Leader
As has been pointed out, this isn't Hackmons. Also, why can't Megas work "normally", assuming 1 is the species and the Mega Stone is in 2?- Allow Megas without Mega Stones (with some exceptions). With Ubers allowed, I believe that allowing Mega Pokemon without the use of Mega Stones encourages more creativity, allowing for the use of Aerilate, as well as the more flexible use of Magic Bounce, Refrigerate, and Pixilate. Of course, Mega Pokemon like the Mewtwos, Rayquaza, Groudon, and Kyogre would be banned, and Diancie, Slowbro, Metagross, and Lati@s seem banworthy as well, though I'm not exactly sure yet.
What do you all think?
