This vibrant swarm loop turns a modest investment of mana into an overwhelming parade of bodies, fueled by Cryptolith Rite granting your entire board the ability to tap for mana immediately upon arrival. While Ant Queen normally requires a steady stream of resources to keep its brood growing, Fervor ensures that every newly hatched Insect token gains haste so it can tap for mana the absolute second it enters the battlefield. The real magic happens with Queen Allenal of Ruadach standing watch: her replacement effect ensures that every single Ant Queen activation doesn't just birth an Insect, but also tags along an extra 1/1 white Soldier token to further pad your mana reserves and swell the Queen's own power and toughness to astronomical heights.
