Why not run Giga Drain instead of Mega Drain?
Have it also run Synthesis with Bold or Calm nature, depending on whether or not you want it to be a special or a physical wall. You can then allocate EVs according to the nature and wall type you chose.
hehehe looks like another pokemon I have to set up an egg move for. Breeding isn't that bad, at least.
Right now its companions are something like:
Greninja (special, not mixed, except
maybe + U-turn if I'm unsure of the defensive capabilities of my team)
Mawile (Intimidate, thinking of giving it Fire Fang. This is the Mega.)
Gliscor (Poison Heal, or w/e tf it's called)
And on the fence with
Espeon (possibly baton passing, at least one screen)
Though I'm fairly convinced Espeon would be helpful. The thing right now is I assume the Venusaur build would impact the Gliscor build, since Gliscor does Toxic-stalling better than Venusaur except Gliscor's physical, and I don't want two Pokemon doing the same thing.
Thanks though. Should definitely slap a Giga Drain on the monster.
