This clever loop transforms a board wipe into a devastating engine by letting Enchanted Evening turn every single permanent on the battlefield into an enchantment. Once that global type-shift is in place, casting Cleansing Meditation wipes away all permanents—including your own lands and creatures—and sends them straight to the graveyard, triggering its Threshold effect to immediately return all of those destroyed cards back to the battlefield. Among the returning permanents is Vampire Charmseeker, whose enters-the-battlefield ability triggers to hand Cleansing Meditation right back to you so you can repeat the entire process endlessly.
