Unsure exact situation so i wont flagrantly object OP
Some thoughts tho:
Opponent not understanding what your deck does ≠ cheating. Its their responsibility to research the meta not yours to teach them in the middle of a game
Short cutting a loop after explaining ≠ cheating
it is absolutely insane that the current best of lux takes advantage of opponents not understanding the deck and cheated his way to 8-1
you can NOT do the power loop as often as the energy loop. judges didn't catch it, hj said the player will not be penalized.
so unfair to the yi
