Sleeper's Robe

Pairing evasion with card draw on a single Aura is the design move here: rather than splitting the two functions across separate cards, this welds an evasive threat to a repeatable refill in the same two-mana investment. Fear handles the connection problem (only black creatures and artifact creatures can interpose themselves), and once the hit lands, the draw trigger turns each successful attack into card advantage. Every Aura carries the same liability, and this one is no exception: enchanting a creature commits two cards to a body that a single removal spell answers, blowing you out on tempo. The blue-black build wants you to discount that risk because the upside is an attacker that both demands an answer and rebuilds your hand each time it goes unanswered. The structural ancestor is the old enchant-a-creature-and-draw template, but folding evasion into the same card is what makes the engine self-sustaining: you are not relying on the creature being naturally hard to block, you are granting that quality and the payoff in one slot. It rewards a cheap, expendable carrier rather than a marquee one, since the Robe supplies everything that matters except a willingness to swing.
