Melffy Staring Contest

•Once per turn, you may reveal a Beast card from your hand. If you do, search your library or graveyard for a Melffy creature card with a different name, reveal it, put it into your hand, then shuffle. Put the revealed Beast on the bottom of your library.
•At the beginning of each opponent’s combat, you may reveal any number of Melffy creature cards from your hand. Until end of combat, creatures they control get -X/-0, where X is the total power and toughness of the revealed cards.
