QC REJECTED 2/3
I never approved Gengar earlier, it just sucks. Even non-Shadow Tag Chandelure does better than Gengar due to the power difference and STAB Overheat. Base 130 SpA is acceptable but Shadow Ball as your strongest usable STAB is shit. Gengar is fast but not fast enough without Choice Scarf, you don't even out speed most Arceus forms. Without a power-boosting item, Gengar is piss weak. I don't even know what you can revenge kill reliably when you are so damn frail and even Mewtwo survives your Shadow Ball.
