By pumping your battlefield with Dictate of Heliod, any 2/2 Zombie token created by Zombie Infestation is instantly elevated to a 4/4 threat, which cleverly bypasses the strict power restrictions of Elemental Bond and Garruk's Packleader. As these giant Zombies flood the board, both drawing engines trigger simultaneously to hand you a steady stream of cards. This creates a self-sustaining loop where the cards you draw feed right back into Zombie Infestation's discard cost, letting you churn through your entire library while amassing an overwhelming undead army.
