At the top of a recursion chain, a 4/4 for seven is selling something other than its body. The soulshift trigger reaches back for any Spirit costing six or less when this dies, which is nearly the entire tribe: the threats that actually close games rather than the one-drops the cheaper links in the chain refill. That is the whole pitch. Cast your most expensive Spirit and dying is never a dead end, because each death stitches the graveyard back into the hand and feeds the next play. Menace is the concession to the weight: at seven mana the creature has to threaten real damage on its own, and forcing two blockers keeps it from being chump-stopped while the recursion waits to fire. The tension is honest. A 4/4 for seven is a miserable rate measured raw, but the soulshift number is not buying the stats; it is buying the loop, the assurance that the top of your curve is always one death from coming back. This is a slow engine wearing a beater's body, and it rewards a deck that treats its own graveyard as a second hand to draw from.
