>>33411375yeah sorry for my oversight since fighting also hits 5 types SE but it's still not possible
let's see
>fighting is the only type SE against normal>ground is the only SE against electric>fairy is only weak against steel and poisonfrom this you'd need a fighting, ground and steel or poison (doesn't matter which since steel is SE against 2 types covered by fighting and poison only against grass which is the least of our worries)
that leaves us with water, fighting, ground, ground, flying, psychic, bug, ghost and dragon
you could go with pre gen VI so no fairies so
>fighting attack>ground attack>dragon is only weak to dragon (which is SE on no other type) and iceice is great for the third slot since with freeze-dry you get 5 more attack you're SE against
however the remaining: fighting, psychic, bug and ghost can't be hit SE by just one move. we'd need a dark move for ghost and psychic and a flying move for fighting and bug
