Ashling, the Limitless enables a powerful sacrifice-and-copy loop by giving Elemental spells cast from hand the option to evoke for a flat five mana, then replacing each sacrificed nontoken Elemental with a hasty token copy that can be kept permanently by paying WUBRG. The deck floods the board with Elementals through landfall triggers, token generation, and enter-the-battlefield payoffs, while effects that double triggers or deal damage equal to a creature's power whenever one enters convert the endless stream of Elemental enters and exits into lethal damage. Sundial of the Infinite enables a key shortcut by ending the turn before the beginning-of-end-step sacrifice triggers resolve, letting the deck keep its token copies for free and build an overwhelming, ever-growing Elemental army.
