Palace Familiar

The two mana buys a blocker that refuses to die for free. A 1/1 flier trades up against ground attackers or holds back something evasive, and when it finally falls (to combat, to removal, to a sacrifice outlet), the dies trigger draws a card so the tempo loss is never a card loss. That draw-on-death trigger is the whole design ethos of the small-blue-flier-with-upside lineage: the body is disposable on purpose, built to be spent rather than protected. A blocker you are happy to lose is a different strategic object than one you must defend, and this is squarely the former. It slots cleanly into any deck that wants bodies to feed a sacrifice engine, since the death trigger turns each sacrifice into a cantrip rather than pure attrition, and the flying gives it a backup plan as a chip-damage clock when nothing wants to eat it. The rate is modest by design: a 1/1 for two does little on its own, and the draw is the payment that keeps the card from being a dead topdeck in the late game. What it offers is consistency rather than impact, the kind of low-variance filler that keeps a curve smooth and a hand stocked without ever asking to be the centerpiece.
