Crystron Rion

Effect

During your opponent's Main or Battle Phase (Quick Effect): You can target 1 of your banished non-Tuners; Special Summon it, but its effects are negated (if any), and if you do, immediately after this effect resolves, Synchro Summon 1 Machine Synchro Monster using only that monster and this card. These Synchro Materials are shuffled into the Deck instead of being sent to the GY. You can only use this effect of "Crystron Rion" once per turn.
