Tasigur, the Golden Fang

Delve made the cost a fiction. The printed six mana is the ceiling, not the floor: in a graveyard-fueled deck this is a turn-three or turn-four 4/5 that costs a single black pip and a pile of exiled cards, and the body is large enough to survive most of the cheap removal that would happily kill a threat landing that early at full price. That tension between a steep face value and a real cost approaching one mana is the whole design, and it landed Tasigur in graveyard and control shells where the cards already spent are the resource that pays for him. The activated ability is the second hook and the quieter one: at two generic plus two hybrid pips that bend Sultai, it mills two and pulls a nonland card back from your graveyard, with the opponent choosing which. Handing the choice to the opponent stops the ability short of a clean tutor, but in a long game it still grinds in your favor: a player with a deep graveyard and a fat board never minds being given the worst of several good options, over and over. He reads as a midrange beater and operates as a slow, repeatable card-advantage engine bolted to a cheap, resilient threat, a strange and durable combination of jobs for one legendary creature to hold.
