Hidden Dragonslayer

Return target creature card from an opponent's graveyard to the battlefield under their control with a duty counter on it. For as long as that creature has a duty counter on it, it is goaded, can't attack you or a permanent you control, and can't block creatures you control.

Cast this spell only during combat on an opponent's turn. Prevent all combat damage that would be dealt to you and planeswalkers you control this turn. Untap all attacking creatures and goad them. After this phase, there is an additional combat phase.

Draw X cards. If X is 10 or more, instead shuffle your graveyard into your library, draw X cards, untap up to five lands, and you have no maximum hand size for the rest of the game. Exile Finale of Revelation.

Enchant creature Enchanted creature has indestructible and is goaded. (It attacks each combat if able and attacks a player other than you if able.) 1W: Exile enchanted creature.

Flying Whenever this creature deals damage, you gain that much life. Morph 2WW (You may cast this card face down as a 2/2 creature for 3. Turn it face up any time for its morph cost.)

Vigilance Whenever Nelly Borca attacks, suspect target creature. Then goad all suspected creatures. (A suspected creature has menace and can't block.) Whenever one or more creatures an opponent controls deal combat damage to one or more of your opponents, you and the controller of those creatures each draw a card.
