Rootha, Mastering the Moment rewards casting high-mana-value instants and sorceries by generating large flying, hasted Elemental tokens at the start of combat, so the deck focuses on casting expensive spells — often fueled by mass mana rituals and delve draw spells — to produce massive threats out of nowhere. Veyran, Voice of Duality doubles triggered abilities, meaning each qualifying spell can produce two tokens, while Brudiclad, Telchor Engineer can convert a board full of diverse tokens into copies of the largest threat present for a lethal swing. Extra turn spells like Alrund's Epiphany compound this pressure by giving the tokens additional opportunities to attack before opponents can stabilize.
