This clever loop centers on casting and recasting Blinking Spirit for free, turning its zero-cost return ability into a self-sustaining engine. Every time you cast the Spirit, Chakram Retriever triggers to untap Sanctum Weaver, whose own tap ability generates an abundance of colored mana fueled by your enchantments. Because Blinking Spirit bounces itself right back to your hand for zero mana, you can continually replay it to repeat the cycle, yielding infinite enters-the-battlefield and leaves-the-battlefield triggers alongside an endless stream of colored mana.
