Crystron Entry

2017 Mega-Tin Mega Pack

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