How do you change your pokemon to be level 100 in Gen 5 wifi battles?

Question

I asked i question if it was posible and appearantly it was but i don't know how, would really appriciate an explenation how to do so.

Answer 1

NO. There was speculation that the battle box does that but it was wrong. There is no way. Flat battle sets lvl 50+ to lvl 50 but only allows 3 single, 4 double, 6 triple. So I suggest Training to lvl. 100 I know it takes forever but thats how it is.
