Special Summon 2 "Crystron" Tuners (1 from your hand and 1 from your GY). During either player's turn, except the turn this card was sent to the GY: You can banish this card from your GY, then target 1 "Crystron" monster you control; send 1 "Crystron" monster from your Deck to the GY whose Level is different from that monster, and if you do, that monster becomes the Level of that monster sent to the GY. You can only use this effect of "Crystron Entry" once per turn.
