New Moves: Body Press, Spectral Thief, Head Smash
The goal of these additions is to turn Super-sized Gourgeist into a viable tank. A boost in HP and Special Defense combined with the removal of its Dark and Ghost weaknesses help out defensively... while the three new move additions help offensively and keep Gourgeist from being set-up fodder. Body Press pairs well with Gourgeist's already solid base defense to put pressure on certain Dark and Steel types like Ferrothron, Obstagoon, and Bisharp. Spectral Thief gives Gourgeist reliable Ghost STAB and stops set-up sweepers in their tracks by stealing their stat boosts. And Head Smash keeps the Fire, Flying, and Ice types that can break it from switching in freely. 4 move slot syndrome sucks though.
Flavor-wise, giving Gourgeist Illuminate is a bit of a reach since the ability translates to Luminescence (creating light without fire/heat). But I can look past it if you guys can.
