Armored Skaab

The defensive body and the graveyard payload are the same purchase here, which is the whole design conceit. A 1/4 stonewalls early aggression: most one- and two-drops bounce off four toughness, buying the time that a self-mill deck needs to assemble whatever it is filling its graveyard for. The mill four on entry stocks that yard immediately, turning the same card that holds the ground into the card that loads the engine. That double duty is rare in a single common: a wall and a fuel source usually cost two cards, and the cards that try to be both often skimp on one half. The catch is that the mill is one-shot and untargeted, hitting your own library with no control over what falls. Decks that want a specific card in the bin get noise, not selection; decks that simply want bulk (reanimation targets, flashback fodder, delirium-style card-type variety, or threshold counts) get exactly the kind of indiscriminate volume they are after. It is built for the strategy that treats the graveyard as a resource pool rather than a precision toolbox, where the body keeps you alive long enough to spend what the trigger deposited.
