Gibbering Kami

Soulshift turns a forgettable flyer into a draw on the way out, and that inversion is the whole reason this body exists: it is built to die well rather than win combat. When it falls, it pulls a small Spirit back from the graveyard, and at four mana it sits squarely in the middle of the recursion ladder, cheap enough to retrieve the early drops it shares a curve with and small enough to be retrieved in turn by the larger Spirits whose soulshift values reach it. The evasion does quiet work here: a flyer that trades or chumps in the air still cashes out a card, which softens the attrition a swarm-based Spirit deck would otherwise bleed through. The design wants these creatures thrown into combat without hesitation, because each death registers as a draw rather than a loss; the individual body matters less than its position in a chain meant never to quite run dry. Structurally, the keyword converts a pile of unremarkable flyers into a self-replenishing engine, and this is one of its plainer, most replaceable links: expendable enough that you never mourn the trade, connective enough that the chain keeps moving through it.
