Raven Eagle

The design bolts two familiar black engines together and lets them feed each other. The graveyard-hate half fires on entry and again on every attack, and it turns each exiled creature into a Clue, so the same action that shrinks an opponent's recursion also stocks the battlefield with a delayed card. That Clue is the pivot: cracking it is the draw that most reliably gets you to your second card of the turn, and that once-per-turn second draw is what drains an opponent and pads your life total. Most draw-count payoffs in black want you to build a whole hand-refill shell around them; this one carries its own kickstarter, because the Clue is a second draw sitting on the battlefield waiting for a cheap window. The flying body is incidental to the engine but not to the plan: a 2/3 in the air keeps the attack trigger churning the graveyard-exile clock and manufacturing more Clues, so the card is doing its work whether it connects or trades. What keeps the loop from running on its own is the "up to one target" clause and the fact that the drain caps at once per turn: you crack Clues in order to reach that second draw, and you only have Clues to crack because the exile trigger keeps producing them. It is a self-contained loop that still needs your other spells to open the door, an aristocrats-style drain dressed as graveyard interaction.
