This ingenious setup transforms a simple creature drop into a self-sustaining engine by turning the entire battlefield on its head with Enchanted Evening, making every single permanent—including the tokens you create—an enchantment. Once this blanket enchantment-type change is active, whenever The Locust God rewards your card draw with a flying Insect token, that token's entry triggers Slumbering Keepguard to scry 1. Thanks to Eligeth, Crossroads Augur, that scry is instantly converted into drawing another card, which loops right back into creating another token and repeating the entire sequence for near-infinite card draw and hasteing creatures.
