A good core that I have found is the following;

@ Sitrus berry
Ability: Pickup
-Belly drum
-Shadow claw
-Extremespeed
-Seed bomb
EVS: 252 Atk/252 Speed/4 HP

@ Black sludge
Ability: Levitate
-Memento
-Will o Wisp
-Sludge bomb
-Thunderbolt/Pain split
EVs: 252 Speed/252 HP/4 SpAtk
Basically this is a core where you have weezing burn for physical attackers and then memento or just straight memento for the special attackers, then you can safely use belly drum on linoone since you cannot be KO'd even at 50%, especially the burned physical attackers. To go with this core you would usually want a gardevoir or drifblim to be a back-up memento, since linoone is the true core of your team. Linoone is only walled by steel types on paper, so you might want a fighting type or attack to go with it.
