Kumena's Awakening
Howling Mine, but with a built-in off-switch you pay for with the board. The symmetrical-draw enchantment is one of the oldest engines in the game, and its central problem has always been that you hand your opponents the same cards you draw. This is the design that answers it without the upkeep tax or the conditional Howling Mine variants tried before: cross the city's blessing threshold (ten permanents on the battlefield) and the symmetry collapses into a one-sided advantage engine that stays yours from that point on. The structure is what makes it work. Before ascend, the card is a Howling Mine you control, a real cost you eat while you flood the board. After, it is a unilateral card-draw machine that no longer feeds your opponents, and the flip is permanent: nothing your opponent does turns the spigot back into a shared one. That anchors the reward to a wide, permanent-heavy game plan rather than a counter or a sacrifice, so it favors decks that hit ten permanents by playing the board out naturally instead of assembling a combo. It is a clean reframe of one of Magic's most-iterated effects: take the format-warping liability of symmetrical draw and convert it into a milestone you earn.
