Pokemon Sun Battle Tree - Pokemon Trainers Red and Blue (No Z-Moves) 

Just a quick "intro" to the Battle Tree before we dive in because I didn't cover it while playing the post-game.
When you reach this place for the first time, you will have to fight either Red or Blue. I show both in this video. Blue is a much better trainer, to be honest!
Afterwards, I show off the "attractions" of the main floor. The judge will recognize your worth as a trainer after you've hatched 20 eggs, I believe. You can use the judge function on the PC to see your pokemon's potential for each stat AKA individual values (IVs).
We check out the rewards, too. Choice items and leftovers are really good in general while the others fall into more specific strategies.
