>>27659456Forgot it was fire/ghost and not mono ghost, Flare Blitz in the last slot instead would be good.
>>27659458+2 252+ Atk Thick Club Marowak Shadow Sneak vs. 0 HP / 0 Def Salamence: 249-294 (75.2 - 88.8%) -- guaranteed 2HKO (OHKO after SR)
UU doesn't have a good all encompassing priority user to match Marowak up against.
252 Atk Salamence Outrage vs. 248 HP / 8 Def Marowak: 186-219 (57.5 - 67.8%) -- guaranteed 2HKO
It'd at least be physically bulky enough to 2hko some things, but the turn of setup, having to hold thick club, weakness to SR, and low speed and spdef will probably kill it.
