During your opponent's Main Phase or Battle Phase: You can target 1 of your banished non-Tuner monsters; Special Summon it, but it has its effects negated (if any), and if you do, immediately after this effect resolves, Synchro Summon 1 Machine-Type Synchro Monster using only that monster and this card (this is a Quick Effect). These Synchro Materials are shuffled into the Deck instead of being sent to the Graveyard. You can only use this effect of "Crystron Rion" once per turn.
Because it gives Crystrons too much staying power as Rion and the non tuner are shuffled into the deck, so it becomes very hard to take them out. But this is only made so easy because of the combo enabler, Genex Undine and her amazing breasts. But she's a big box UR so it's easier to hit the N, so some remove from play decks that use this card to help recycle their monsters are also affected.
why I cant summon my banished monster using its effect,during opponent turn, neither in main phase or battle phase, is this card bugged?
