Marvo, Deep Operative

Whenever a creature you control that was turned face up this turn deals combat damage to a player, draw a card. T: Turn target face-down attacking creature you control face up.

When this artifact enters, surveil 1. 2, Sacrifice this artifact: Choose one — • Cloak the top card of your library. • Goad target creature. • Draw a card.

Flying, vigilance Whenever you surveil, put a +1/+1 counter on Mirko. At the beginning of your end step, you may return target creature card with power less than Mirko's from your graveyard to the battlefield with a finality counter on it. (If it would die, exile it instead.)

You have no maximum hand size. At the beginning of your upkeep, investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") Whenever you draw your second card each turn, put two +1/+1 counters on Morska.

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.

When Duskana enters, draw a card for each creature you control with base power and toughness 2/2. Whenever a creature you control with base power and toughness 2/2 attacks, it gets +3/+3 until end of turn.

Flying, lifelink Whenever you cast a noncreature spell that targets only Feather, you may choose any number of other creatures that spell could target and pay 2 for each of those creatures. If you do, for each of those creatures, copy that spell. The copy targets that creature. (Copies of permanent spells become tokens.)

Whenever Marvo attacks, clash with defending player. (Each clashing player reveals the top card of their library, then puts that card on their choice of the top or bottom. A player wins if their card had a greater mana value.) Whenever you win a clash, draw a card. Then you may cast a spell from your hand with mana value 8 or less without paying its mana cost.
