Baru, Wurmspeaker

Wurms are one of green's oldest punchlines: enormous, ground-bound bodies that cost a fortune and do little but hit hard, tribal support that never arrived because nobody wanted a payoff for a tribe with no early game. The anthem here answers the second-biggest problem (a 4/4 token becomes a 6/6 trample, large enough to matter) without pretending to fix the first. The cost-reduction ability is the real engine, and the way it reads is the trick: the discount checks the single greatest power among your Wurms, not the total or the count. That distinction matters more than it looks. A lone 6/6, buffed by the anthem, reduces the activation by six, leaving : still real mana, but a fraction of the printed price. Make ten more Wurms and it costs exactly the same, because the greatest power has not moved. The way to squeeze it, then, is not to swarm but to grow: pump one Wurm past the anthem's baseline (a stray +1/+1 counter, another green buff, a card that scales power) and the generic reduction eats deeper, though the in the cost never goes away and the caps you at one token per untap. So it is a payoff card that carries its own enabler, uncommon for a tribal lord: most hand you the +2/+2 and leave you hunting for bodies, while this one manufactures them and pumps what it made. The whole design hangs on getting one Wurm big enough to cheapen the rest.
