Trickster Ball Hoopa Hoopa - MIL0

Guide

When playing Hoopa, lots of people like the Hyperspace Hole. However, trick serves as an instant shield and X Speed, plus a second Shadow Ball. When tricking, ideally do it with a long-distance attacker who won't get themselves killed to preserve your shadow balls.

Early Game:
Just focus on farming until Shadow Ball is unlocked, and then you can start to play a bit more aggressively. However, don't overextend without a friend, especially in the absence of Trick. Wise Glasses + Shell Bell will keep you on the field a bit longer, but still don't be too aggressive.

Middle Game:
Now that you have trick, stick with an attacker such as Gardevoir or Cramorant to benefit from the Trick + Shadow Ball combo. Rings Unbound is useful for objective completion such as goal capture or Zapdos in the late game. Never stray from your partner, and go back if you start to get to low health with trick.

Late Game:
Again, stick with your partner. If at a high level, trick will heal you, so more aggressive plays can be made. When becoming Unbound, make sure at least three quarters of your health is available to make full effect of the health boost.

I don't normally play supporters, so this build may not work as i have very limited experience. If it doesn't work, I'm sorry. Do check out my other builds though! My Gardevoir is featured, so that's nice. Have fun playing!
