This ingenious loop centers around Springheart Nantuko enchanting Dryad Arbor, turning every land drop into an engine for an exponential army. Because Dryad Arbor functions simultaneously as both a land and a creature, its entry triggers the bestow aura while its new status as a creature allows it to be copied right back. Regal Behemoth supercharges the math by doubling your mana production whenever you tap lands while holding the monarch, cleanly funding the repeating {1}{G} payments needed to keep the cascade going. Dragonlord Kolaghan stands ready in the command zone or 99 to give your massive horde of newly minted tokens immediate haste, turning this botanical replication into a devastating, game-ending storm.
