Go wide and fast - imps, powries, raiders - and give it all Charge with War Horse. The knights hold the middle, the deserts ping blockers off their squares, and the courts tax their answers on the way in. When the board clogs, Black Plague or Great Famine resets it. Your side is cheap to rebuild, theirs isn't. Major Explosion and Balor give you reach to finish. The mask is the fun part: pay 3, banish an avatar from the collection, wear its ability until damaged. Don't do it early into open removal - save it for the turn it actually swings the race. Mix Ignis is for the last push through.
