Screeching Skaab

The graveyard-as-resource enabler in its most disposable form: a body that pays for itself in mill before it ever blocks. The 2/1 is almost incidental; what the design buys is two cards into the bin at enters-the-battlefield, with the creature left over as a free attacker or chump. That makes it a quiet workhorse for any deck treating its own library as fuel: self-mill graveyard strategies that want bulk in the yard fast, delve and threshold-style payoffs that count cards regardless of how they got there, reanimation lists hoping to land a target. The cost of the engine is built into the rate. You pay two mana for a fragile creature and a one-time, non-repeatable trip to the graveyard, so the card asks to be run alongside payoffs that turn that bin into something rather than a deck simply digging for nothing. Compared to the dedicated mill-and-attack creatures of the same lineage, this one keeps the mill modest and the body forgettable; its job is volume and tempo, a cheap reusable-only-once shovel rather than a centerpiece. The interesting tension is that the same effect that makes it valuable to a graveyard deck makes it actively harmful to a deck that just wants a 2/1, which is exactly the line that defines whether a self-mill enabler is a tool or a liability.
