Description: Discard 1 card, then target 1 face-up monster you control that has a Level; send it to the GY, also, after that, if it left the field by this effect, Special Summon from your Extra Deck, 1 "Masked HERO" monster with the same Attribute, but a higher Level than, the Attribute/Level the monster had when it was on the field (its original Attribute/Level, if face-down).
