Songbird, Sonic Screamer

The self-discard evasion grant is the entire hinge of this build, and it puts a small, aggressive body on a clock the pilot controls. A 2/1 with lifelink wants to connect: the drip only matters when the damage lands, and a two-power ground creature stalls the moment the board develops around it. The flying grant answers that, but the payment is telling. Spending cards rather than mana means the ability scales with a full grip and evaporates as the game grinds on, so the aggression is front-loaded by construction. It also rewards a build that treats the discard as fuel: reanimation shells, madness effects, and graveyard payoffs all convert what reads as attrition into upside. As a two-mana black attacker with a self-contained evasion outlet and a life-drip, she sits in a well-worn lineage of cheap black beaters that need to keep swinging, but the self-discard clause narrows who wants her: not the deck hunting raw stats, but the one that already stocks its yard and has a reason to spend cards there. Because the flying only has to be paid for on the turns the ground clogs, the question she poses is whether your deck already wants to be pitching cards. If it does, she is a closer. If it does not, she is a fragile 2/1 paying tuition to swing.
