Counter-Magic 4

Desperately, he threw spell after spell into the mass of shambling dead, all to woefully meager effect. Driven only by hunger, they lacked any sentience for his mind to command; drawn by the scent of his life itself, they refused to be slowed or hindered by even the most intricate illusions. And Jace could summon nothing so potent that it wouldn't swiftly be slain by the storm, not without dropping his concentration on the mystic shield that protected his own body from those dreadful gusts.

He struck, instead, at the magics animating them, rather than at the undead themselves. Focusing as intently as he dared, he unraveled the chains of mana that bound a fragment of the soul to these lurching bones, that allowed lifeless joints to bend and dead muscle to flex. Stabbing his hand outward as though hurling a spear, Jace dispersed the mana within first one of the crawling zombies, then the next. They slumped, limp and truly dead as they long should have been.

But still they came, and still he retreated, and each time he severed the last remnants of life from one, three others had advanced upon him. Jace was swiftly tiring, for these were no simple necromantic spells he was countering, but the natural order of things in this impossible realm of Grixis.
