This clever loop transforms a humble land into a self-sustaining engine by letting Maskwood Nexus grant all creature types—including Ally—to Dryad Arbor as it enters the battlefield. This triggers Haru, Hidden Talent to earthbend Dryad Arbor into an animated land that keeps its creature status, allowing you to tap it for green mana before feeding it to Phyrexian Altar for any color. Because the earthbent land is destined to return to the battlefield tapped whenever it dies, you can endlessly cycle Dryad Arbor through the graveyard to continuously generate infinite colored mana, sacrifice triggers, and landfall events.
