>>43374440im shocked that you're putting this much thought into it
but yeah that sounds like the right idea. abuse the bulk and physical attack as much as possible
for the last move
wood hammer would be strong and cover a few more types. but it's resisted by a lot of shit and then every move is resisted by poison
payback is a nice 100 damage and lets it fight ghosts that it would otherwise be worthless against
bulldoze helps against fire types technically but i think it would still be utterly useless against most of them
it can't do shit to flying, which is its other quad weakness.
