Since ORAS is coming out later this year, I want to see your guys' ideas for megas! Leave te pokemon, design possibilities, type changes, abilities, etc! Just try to keep it somewhat realistic!
Swampert wouldn't get sap sipper its just too broken, i can see him getting sand rush or something like that for a speed increase as for stats he'll probably get an attack increase by 30 with both defs going up by 50 with no other changes. Sceptile will probably get either Grass/Fighting or Grass/Dark with an spatk and physical atk of 70 and a boost in defs in by 20 with a speed decrease in 10 probably with adaptability or chlorophyll.
