Kodama of the Center Tree

The payoff that names the entire Spirit deck and sits at its center. Power and toughness equal to the number of Spirits you control means an empty board hands you a 1/1, and a developed one hands you a finisher that grows with every kami and every legendary Spirit you've already cast. That self-counting body is the obvious half; soulshift X is the half that makes the design cohere. Most soulshift creatures fire for a fixed number, retrieving one specific small Spirit on death. Here the trigger scales the same way the stats do: in a wide board the threshold climbs high enough to reach back for almost anything in the graveyard, so the one card you return tends to be the most expensive Spirit you've lost rather than a forced bottom-of-the-barrel pick. Both halves want the same resource (raw Spirit count) and reward it without stepping on each other: one converts width into a threat, the other converts the Kodama's own death into a replacement chosen from the deepest part of the yard. It is the rare tribal payoff that doesn't pump the team but becomes the team's mirror, a creature whose value is just a readout of how committed you are to the plan. Build narrow and it's a small body with a small soulshift, doing almost nothing; build the deck it was made for and it's both the anchor and the recursion engine.
