I would like to discuss the viability of this fairly gimmicky set:
Last Resort
########
name: Last Resort
move 1: Fake Out
move 2: High Jump Kick
move 3: Last Resort
ability: Limber
item: Lopunnite
evs: 252 Atk / 4 Def / 252 Spe
nature: Jolly
After a teammate gets KOed by a Pokemon that is 2HKOed by a combination of Fake Out and High Jump Kick, send in Lopunny, Mega Evolve, use Fake Out, and follow up with a High Jump Kick. From there on, you may proceed to spam Last Resort and High Jump Kick; the two providing decent coverage alongside one another. Thanks to Scrappy, this set is not walled by Ghost-types.
