(Could you help me redo Gardivior's moves? I noticed they are really poorly balanced but I have no idea how to fix that.)

Gardivior whirls and uses moonbeam close by.

(Okay, Moonblast, Heal Pulse and Draining Kiss are all Fairy type moves, while Future Sight is Phycic. As a Phycic/Fairy type, her weaknesses are Steel, Poison, and Ghost types. Here's what I think would work instead:

-Heal Pulse (Fairy type. To heal partners)

-Draining Kiss (Fairy type. To heal herself and deal some STAB-boosted damage)

-Phycic (Phycic type. Reduces target's Sp. Def. and deals a solid amount of damage. Also, STAB-boost and super effective against Poison types.)

-Any TM move for the last slot, for extra type coverage. So, no Fairy or Phycic moves. I'd reccomend a Ghost (To deal with Ghosts) or Fire (To deal with Steel) type move, like Shadow Ball or Mystical Fire.)

(Thank you Heal Pulse, Draining Kiss, Phycic, and Shadow ball it is)

(No problem!)

Slide took the hit before retaliating with Metal Claw.

Gardivior uses pyscic hoping to hit.

Slide dodged with Dig.

Gardivior frowns hoping to make things more intresting then just aim and miss. After a few seconds she jumps up and lands hard on the ground. Not hard enough for a move but hard enough to hopefully trick Slide into thinking it was.

Slide broke the surface of the ground, hoping to land a hit from underneath.

Gardivior notices first and uses shadow ball.

Slide tumbled back at the blow, but she was nowhere near done yet. Hopping back to her feet, she spun around and used Swift.
