YuGiOh! - Chthonian Ruler

Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand or GY) by banishing 2 DARK Fiend monsters from your GY. If this card is Special Summoned: You can target 1 card on the field; banish it. If this card is banished: You can add 1 "Chthonian" Spell/Trap from your Deck to your hand. Once per turn (Quick Effect): You can roll a six-sided die; banish up to that many cards from either GY, then this card gains 300 ATK for each. You can only use each effect of "Chthonian Ruler" once per turn
