>>22103936For doubles, you should maybe also opt for using Helping Hand since he learns that now through move tutirs.
Also Drain Punch over Hammer Arm is a must need, he feels so fucking great with it.
Otherwise, I would say for singles run:
252 HP and Def, 6 Atk
Leech Seed
Drain Punch
Spiky Shield
Filler (can be Spikes, Seed Bomb, Synthesis, etc.)
He's a fucking monster in Maison with that in ORAS.
For doubles, the same set except for the filler, use Helping Help.
