That knocks off three essentials.
I like having a full squadron of possible super effectives but Gardevoir is fucking OP with a counter to dragon, rock and a knife to stab every type in the game several times and have them run the risk of going braindead and injuring themselves.
No need to hunt for a fairy type, just look for any of the pokemon in the Ralts line and evolve them into Gardevoir. They'll get STABs for fairy attacks.
Also, the description.
