Spreezy

Candy

Set 1 (set 2 is better I think)
Moves: Pheroblast, Provoke, Poison Barbs, Pestilence

Item: Health Amulet

Ability: Hard Candy

Personality: Robust, Clever, Very Frail

TPs: 200 HP, 200 Melee Defense, 96 Energy, 4 Ranged Attack/Ranged Defense

Reasons
Pheroblast and Life Drain are the main ways to deal damage for Spreezy. Provoke can cripple Terraflies that try setting Poison Barbs. Poison Barbs helps Spreezy assist the team with hazards.

Hard Candy makes it so that Spreezy has an advantage over Melee Attackers and can easily set Barbs and put Pestilence on them.

Health Amulet is the best item to heal, and if you can't use one, then you might need to change the energy to use Heavy items.

Set 2 (very robust)
I stole this from the internet https://www.youtube.com/watch?v=uXiDzY3Ta0I

Moves: Pheroblast, sap plant, talent trade/poison barbs/provoke, powerfocus/ poison barbs/provoke
