Lightray Diabolos (Common)

Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) by having 5 or more LIGHT monsters with different names in your Graveyard. Once per turn: You can banish 1 LIGHT monster from your Graveyard, then target 1 Set card your opponent controls, reveal that target, then place that target on either the top or bottom of the Deck.
