Devoted Combo relies on Devoted Druid plus Vizier of Remedies for infinite mana and Green Sun's Zenith to tutor pieces, so Rest in Peace disrupts Agatha's Soul Cauldron and any graveyard recursion like Fiend Artisan while exiling their yard outright. Mystical Dispute is a cheap way to counter their rare blue-adjacent picks and generically stop key green spells like Nature's Rhythm for 3 mana, disrupting their combo assembly. Kaheera provides a resilient beater that dodges their small creature removal suite. Cut slow card selection and the situational two-drop counter since proactive hate and efficient interaction matter far more against a combo deck trying to go infinite.
