Mega Tyranitar + Sand Force: Uhhh, this is horribly broken. Sand Force with that Attack and boosted SpD from the Sand with a DD set? Yeah, it's like Sand Rush Mega Garchomp all over again.
Mega Sceptile + Technician: So, it gains Dragonbreath as a usable STAB (stupid 30% paralysistotally not Scald) as well as a stronger Hidden Power. If you want to, you can run the SD set with physical moves. The loss of Thunder Wave immunity hurts though.
Tangrowth + Grass/Rock: Losing resistances to Ground and Water to trade for a neutrality to Fire and Flying? Still meh since Talonflame still beats it.
Forretress + Water Absorb: Not too sure about this. Keldeo still Calm Minds or Subs freely on it. MegaBro can run Fire Blast or wear it down with boosted Psyshocks. Azumarill Drums in front of it and kills with Knock Off. The slow Volt Switch can be useful but Forretress is still set-up bait to the things it's supposed to beat.
