Devoted Combo has almost no interaction for us (no counterspells, no discard) so this is a pure race — we typically win by simply comboing before they assemble Devoted Druid plus Vizier of Remedies. Engineered Explosives at low X sweeps their one and two mana dorks (Delighted Halfling, Badgermole Cub, Devoted Druid, Birds of Paradise) to slow their mana engine, and Tormod's Crypt can strip Agatha's Soul Cauldron fuel or Fiend Artisan graveyard plans. Stern Scolding and extra Spell Snare are weak since their key pieces (such as Green Sun's Zenith targets) often dodge counterspells or aren't worth tempo-negative answers when we should just be goldfishing.
