Sanguine Syphoner

A drain trigger welded to the attack step, which is quieter than the effect implies. Most incremental-drain vampires prefer to sit back and grind; this one only pays when it turns sideways, so the single point of life-swing is bought by committing a 1/3 to combat every turn. That toughness is the whole rationale. It survives most one-toughness sweepers and trades up against small aggressive creatures, so it can keep swinging into a stalling board where a 1/1 or 2/1 version would have died turns earlier. Note the timing: the drain fires when it declares an attack, not when it deals damage, so a chump block still costs the opponent a life and pads yours. A single swing produces a negligible drip, the kind of number that only matters once you repeat it: multiply the attacker, copy the attack trigger, or fold it into a wider aristocrats shell where every point of life-swing feeds another payoff. Left alone it is a slow clock. Stacked, the attack-gated life differential (opponents down, you up) does the same closing work that lifegain-and-drain engines have always done in mono-black and Rakdos midrange, just conditioned on your board actually pressing forward. As a common-rarity role-filler it earns its slot in a tribal aggro shell that wants bodies which also chip at a life total, not by being a marquee vampire but by being cheap, hard to kill, and relevant on every attack.
