Sound the Call

The Wolf token reads the graveyard for copies of the very spell that made it, and that loop (a creature counting the castings that produced its kind) is the whole engine. Because the resolving spell goes to the graveyard immediately after making the token, even a single copy nets a 2/2: the static ability sees the spent sorcery sitting in the bin and counts it. The growth compounds across copies and across players, since the ability tallies every Sound the Call in every graveyard at once. Cast a third copy with two already binned and all the Wolves swell to 4/4 the moment that third spell finishes resolving and joins them. The payoff is communal rather than personal: the bonus spreads across the whole pack instead of stacking onto one body, and any earlier Wolves grow alongside each new addition. The design leans on a quirk most token-makers ignore, namely that the spell wants to be in the graveyard as much as on the stack, so discard, self-mill, and simply casting more copies all feed the same count. A green sorcery that escalates off repeated castings was unusual for an era when green's relationship to the graveyard was about returning creatures from it, not rewarding cards left lying in it. What it asks for in exchange is total commitment: it wants you to run all four copies and want very little else, because a lone Sound the Call is a thin payoff for the slot.
