Gardevoir

Gardevoir's main niche comes from its useful utility moves in Trick and Healing Wish, which give it a notable advantage over other Choice Scarf users in the tier like Heracross, Xurkitree, and Flygon. Alternatively, Choice Specs lets it break past walls like Registeel and Assault Vest Reuniclus. However, Gardevoir is rather slow for a Choice Scarf user, so it can't revenge kill most other Choice Scarf users in the tier such as Heracross, which can easily pick it off with minimal chip damage. It struggles to directly switch into attacks, especially since its Speed can force it to take another attack before moving. Gardevoir faces competition from other Choice Scarf users like Flygon, Heracross, and Togekiss.
