Call the Scions

Two bodies and two units of stored mana for three: the rate is unremarkable, but the Scion is the point. Each token carries its own ramp built into its death, so the spell is simultaneously a board presence and a deferred Rampant Growth split into halves you cash in on your own schedule. That flexibility is what separates the Eldrazi Scion from its smaller cousin the Eldrazi Spawn, whose tokens only ever made a single colorless and could not contribute to combat the way a 1/1 can. The colorless mana matters: it is the specific resource the largest Eldrazi demand, so a board of Scions is a slow toll being collected toward casting something that costs eight or ten. The devoid line keeps the card colorless despite the green casting cost, which is less a gameplay lever than a flavor commitment to the idea that these creatures belong to no color's identity. The real tension the design resolves is the gap between fodder and acceleration: a sacrifice outlet wants bodies, a ramp deck wants mana, and a token deck wants width. Call the Scions feeds all three from one slot, which is why the Scion token has outlived nearly every spell that made it. The spell is the delivery system; the resource it stocks the board with is the part that keeps mattering several turns later.
