Jeskai Ephemerate grinds value with Mulldrifter and Augur of Bolas blinked by Ephemerate, backed by Counterspell and Skred for interaction and removal, so you want resilient threats that punish tapped-out or reactive turns rather than committing your whole hand at once. Shattered Acolyte, Tilling Treefolk, and Saruli Gatekeepers all provide efficient, hard-to-two-for-one bodies and incremental life gain to offset their card advantage engine. Cut the clunkier ramp pieces for more action since flooding out against a deck this grindy is a losing proposition. Be mindful of Skred scaling with snow lands, so avoid overcommitting your biggest single threat into open mana late game.
