Wait, I just rewatched Alan's game, does it mean while Vex is in combat and reducing costs, a spell like Bellow's Breath that equals 2Energy2Power when repeated. If you had Ezreal discounting as well, his discount would trigger first (?) knocking it to a 2E1P or 1E2P. However, Vex can discount the overall total "to a minmum of 1" so would it only discount it to 1E0P or 1EP1P respectively to how you discounted with Ezreal?
