for those with an impish or adamant lunala,here ya go.
shadow shield+(ghostium,psychium,flyium z)/leftovers/colbur(dark)=kasib(ghost)berry
252 hp /252 def(atk) /4spe(def,atk)
+roost/moonlight(for a sun team if you dont wanna use roost-)
+phantom force/acrobatics/psyshock(any of these moves work best or if you wanna go for a skill swap pixilate,refridgerate,return or giga impact.
+cosmic power(for even more bulk,and to stall your opponent into wasting pp)
+toxic/will-o-wisp/thunder wave(i recommend toxic to further weaken your opponent,and upon them switching,(if they do,and keep on switching,
)all of the teams will be poisoned.
lunala really is nice for a bulky staller,but with an adamant one (or impish or careful-) one,youre only limited to a few physical moves like aerial ace,sky drop,sky attack,fly,acrobatics,shadow claw,phantom force and return or giga impact.
if only lunala learned as a tutor move zen headbutt,then she could of had another coverage move for fighting and poison types. but I guess you can count psyshock as a physical move considering that it only affects the defense stat of an opponent. (knowing its a special move)
