The most deadly fairy you will ever meet
item: Chople berry/ enigma berry
Focus Blast/Thunder/Thunder bolt/Fire Blast/Flamethrower/Ice Beam/Blizzard/Metronome/Psychic
Best worked with a 'lure' pokemon in double battles because they will want to take that out. Stored Power gets some decent boosts from Calm mind. Moonlight heals you up. The remaining moves are up to you but the ones above are recommended, but be careful with Metronome. The chople berry reduces fighting moves by 50% but enigma berry will heal you if hit by one.
