This clever loop transforms a simple bounceland into a relentless engine by turning the entire board into enchantments via Enchanted Evening. When you drop Rakdos Carnarium, its native entry trigger fights for the stack alongside Composer of Spring's constellation ability, which happily rewards you every time a new enchantment arrives. By resolving the bounceland's return trigger first, you bounce Rakdos Carnarium right back to your hand so Composer of Spring can immediately cheat it back onto the battlefield tapped. This creates a continuous, self-sustaining loop that generates infinite landfall triggers without ever letting the land settle down.
