I think I got something going with this core. What do you guys think?

Okay, I know there's a Heatran / MegaSaur core on this thread somewhere, but I don't care. These two have nearly perfect synergy with each other, Heatran taking Flying and Psychic-type attacks for MegaSaur, while MegaSaur can switch in to Water and Fighting-type attacks aimed at Heatran, and is only neutral to Ground-type attacks. Mega Venusaur is more Specially Defensive so it can take on threats like Rotom-W easier. Greninja can easily be thrown into this core, as it's pre-Protean weaknesses are covered by the other two. Offensive Heatran is still a nice Pokemon this gen, but I'm not sure if I should run Flash Cannon just for Fairies, seeing as Stealth Rock is important for securing OHKOes, as well as MegaSaur running Sludge Bomb. Extrasensory is the better coverage move over Grass Knot on Greninja, as it smacks opposing Mega Venusaur and Tentacruel very hard.
252 SpA Life Orb Protean Greninja Extrasensory vs. 252 HP / 252+ SpD Tentacruel: 187-221 (51.3 - 60.7%) -- guaranteed 2HKO after Stealth Rock and Black Sludge recovery
252 SpA Life Orb Protean Greninja Extrasensory vs. 252 HP / 252+ SpD Mega Venusaur: 187-221 (51.3 - 60.7%) -- guaranteed 2HKO
Stealth Rock isn't really a factor for Tentacruel, seeing as it usually never runs max Special Defense. I do realize that these three are all walled by Goodra, Chansey, and Blissey, but Assault Vest Conkeldurr deals with those three.
Conkeldurr @ Assault Vest
Ability: Guts
EVs: 252 Atk / 8 Def / 248 SpD
Adamant Nature
- Drain Punch
- Mach Punch
- Ice Punch
- Knock Off
Conkeldurr is more than willing to switch in on a status move, gain a Guts boost from it, and then proceeded to smash the Special Walls with its attacks. With Guts, Blissey is OHKOed by Drain Punch, while Goodra and Chansey are 2HKOed by it. In addition, its weaknesses are covered by Heatran, which is another plus.
