Speed: 20 (-20)
Ability: Water Absorb
Water Absorb's hella unlikely but if it does get it it would actually be pretty amazing. A bulky set with Will-o-wisp/Fire Blast/Earth Power/Filler would be able to take on a lot of top shit like Azumarill, Thundurus, Greninja, Rotom-W, Bisharp, Mega Mawile, Aegislash, and Mega Scizor. Even without Water Absorb it will probably still be okay as long as they focus on its bulk.
The one I'm worried about still sucking even with a mega is Sharpedo. They'd have to do something drastic like draining 50+ points from its special attack to save it. Something like:
HP: 70
Attack: 150 (+30)
Defense: 90 (+50)
Sp.Attack: 35 (-60)
Sp.Defense: 90 (+50)
Speed: 125 (+30)
