Triple/Double battle utility
Ability: Telepathy
Heal Pulse -heals the acual attackers
Wish/Reflect -wish combos with ally switch pretty well, while reflect boosts the teams defense
Ally Switch/Telekinesis -ally switch lets gardivoir take a hit for a teammate(which with these ev's, it should be able to take the hit) and gives them a wish, it could also be very confusing for your opponent, or telekinesis makes the opponent easier to hit
Psychic -your not total taunt bait
252 Defense - helps with that subpar defense
126 SpDefense - boosts that already stelar SpDef
126 Speed - makes sure that you can go to work before something bad happens
4 HP -just because
I have no clue what item to use
