This is what Haxorus looks like from the beginning.
Can someone give me an answer to this unsolvable problem?
(Also. There are no Support Pokemon in the beginning, just those three.)
There's video here that shows you how to solve this puzzle.
Follow it step by step and you'll get through; I really don't have anything to add to that. The Haxorus level is probably the only true puzzle of the entire game so far.
