Okay, so let's get right into the topic.
This is the set up I plan for Gourgeist. First, let's see it's stats.
Gourgeist (Super Size)
Sp. Atk: 58
Sp. Def: 75
Let's look at my planned EV spread.
252 Sp. Def
6 Def (I might have made a mistake and I'm sorry)
The item will be the Assault Vest.
The move set is shown below.
How does this set sound? More importantly, should I have an Assault Vest on Gourgeist?
