Shessra, Death's Whisper

Two payoffs stapled together at a body that fights neither. The enters trigger is a forced block, which is not really about combat math: it is a way to steer a creature into your attack on your terms, feeding the end-step draw off your own combat even when the opponent would rather hold everything back. That closes the loop most repeatable card-advantage engines leave open, since you can lean less on a sacrifice outlet or a lucky trade to make death happen; you can set it up with the same trigger that puts Shessra on the table. From there the design is a slow, self-limiting drain: two life for a card, but only on turns something died, and only at your end step, so it rewards a board built to trade rather than a hand held in reserve. The 1/3 frame is the honest part of the deal. This is a value hub that wants to sit back and count corpses, not a threat you race with, and pricing it as a fragile-but-durable blocker keeps the draw engine from being free. What it represents is the golgari attrition commander in miniature: the color pair has always wanted to convert creature death into cards, and here the death-manufacturing and the card-drawing live in one four-mana package instead of across an assembled engine.
