Shadow Trick Build Hoopa - DecimatedSoul

Guide

Magician - Passive Ability
In battles where the map is divided into an ally team side and an opposing team side, this ability creates a hole under one of the berries on the opposing team's side (chosen at random) and warps it in front of Hoopa (40s cooldown). If there are no berries, but there is Aeos Energy on the ground, then some energy is warped in front of Hoopa instead. In the event that no berries from the opposing team's side are warped, the cooldown of this ability is reduced to 20s. Berries last 30 seconds and take 2 second to appear after magician's activation.

Attack - Auto Attack
Becomes a boosted attack with every third attack, dealing damage to enemies by unleashing a beam of light.
Damage - Basic: 100% Atk + 0 x (Level - 1) + 0
Damage - Boosted: 53% SpA + 8 x (Level - 1) + 160

Shadow Ball - Ranged (4.5s cd)
Level 6 - Unleash a shadowy blob in front of Hoopa, dealing damage to enemies hit and decreasing their movement speed by 50% for 1s and Sp. Defense by 30% for 3s. If Hoopa then hits the same enemy with a move or boosted attack within 4s, deal additional damage and leave the enemy unable to act for .8s. When using this move, if there is a nearby ally linked by Trick, this move will also unleash a shadowy blob at the same target from that ally's location.
Damage: 100% SpA + 0 x (Level - 1) + 300
Damage - Additional: 25% SpA + 0 x (Level - 1) + 75
Level 12 - The shadowy blob will now explode before disappearing. Enemies hit by the explosion are affected as if they were hit by the shadowy blob itself.

Trick - Buff (7.5s cd)
Level 4 - Hoopa creates a link between itself and an ally, increasing both of their movement speeds by 70% for 3s and granting them each a shield for 3s. For the next 7s, when Hoopa uses Shadow Ball or performs an auto attack, the ring on the linked ally also unleashes the same move or attack and if both attacks hit the same target, the second deals 50% damage. Hoopa can also use this move on themself, increasing movement speed and granting a shield for a short time. Additionally, increase the damage dealt by Shadow Ball while Trick is active.
Shield: 200% SpA + 30 x (Level - 1) + 600
Damage - Shadow Ball Bonus: This can trigger multiple times. 10% SpA + 0 x (Level - 1) + 30
Level 10 - Hoopa and the linked ally each heal for 10% of their own damage dealt. This effect lasts for 3s.

Rings Unbound - Buff (112s cd)
Level 9 - Hoopa becomes invincible for 0.6s while transforming into Hoopa Unbound, then becomes unstoppable for 0.3s as it opens a large portal ring at a designated location. Hoopa Unbound lasts for 15s, increasing max HP by 40% and changes Hoopa's regular moves to Hyperspace Fury and Psybeam. Hoopa Unbound cannot score goals or activate the Magician ability. The portal ring created stays open for 10s, and allies can warp to that location once within the duration of the ring. This portal is indicated on the mini map where all players may see where it is.
