Probopass-gyro ball would be perfect for him if he had higher attack, but he can't learn it so...
TOXIC!!- given
block- yeah
protect-stalls even further
taunt/hidden power[grass]/stealth rock/sandstorm/earthquake/magnet rise.-taunt to prevent the foe from taunting you, Hp for type coverage, stealth rock/sandstorm for added damage with toxic, or flash cannon or earthquake should he need to attack with STAb, I don't see the point in giving him moves for type coverage since he won't be able to take them out with his low speed and offensive stats. or MR if you don't want ground attacks.
In my opinion, his offenses are too low for any attacks to be worthwhile.
