[LOOKING FOR] Battle Tree Pokemon

[Dimmsdale]

I'm looking to get 3 good pokemon(4-5IV's preferably) to help me through the Battle Tree to get Mega stones, etc. 
I would LOVE a Bagon, but any assortment works. 
A few of my more noticable pokemon I would be willing to trade are:
Mewtwo
Luxray-Shiny
Meloetta-Shiny
Lunala
All Ultra Beasts
Silvally
