By enchanting Kiki-Jiki, Mirror Breaker with Pemmin's Aura, you unlock a brilliant mechanical loop that bridges a creature-duplicator and an unexpected mana producer. Because Crosis's Attendant is a nonlegendary creature, Kiki-Jiki can churn out endless hasty token copies of it for free. Each token can then immediately be sacrificed to fund its own ability, yielding three mana for a mere one-mana investment. Crucially, the blue mana generated by Crosis's Attendant pays right back into Pemmin's Aura's untap ability, leaving you with an unstoppable surplus of red and black mana alongside endless enters-the-battlefield and death triggers.
