Now, Obstagoon is my favorite SwSh Pokémon, and I designed a moveset just for it. The ability is Guts, which raises attack when inflicted with a status condition. That is what the Flame Orb is for.
Now, the EVs in attack and speed is to make this a killer. The 52 Hp is to help it survive the Flame Orb longer. The Jolly or Adamant nature is to increase speed and attack, your choice on which one.
Obstruct is to avoid a deadly attack or to buy time. Knock Off is a great move to have, and you should almost never pass in having it on a Pokémon. Throat Chop is the highest damaging dark type move Obstagoon can learn, and it gets a STAB bonus. And the final move is really whatever you want it to be, it doesn’t really matter. But I do suggest going with whatever is there. Double Edge is a good move, and it gets a STAB bonus, Close Combat and Gunk Shot have coverage and are powerful, and the same for the 3 punches, just a little weaker.
