Jain, Twilightsworn General (COTD-EN024)

Once per turn: You can banish 1 "Lightsworn" monster from your hand or GY, then target 1 face-up monster on the field; it loses ATK and DEF equal to the banished monster's Level x 300, until the end of this turn. Once per turn, if your other "Lightsworn" monster's effect is activated: Send the top 2 cards of your Deck to the GY.
