This looping engine turns your hand into an endless army by letting Graaz, Unstoppable Juggernaut fundamentally rewrite the biology of your entire team, transforming every token into a 5/3 Juggernaut upon arrival. Because their base power is thus elevated well past the necessary thresholds, every 2/2 Zombie creature token churned out by Zombie Infestation immediately satisfies both Garruk's Packleader and Garruk's Uprising, triggering a double-draw bonanza that replenishes the exact cards you need to feed back into the Infestation. The result is a self-sustaining cycle of discard, creation, and card draw that buries your opponents under a tidal wave of massive undead juggernauts.
