Aqueous Form

Unblockable as an Aura, sold for one blue mana, is a deal a long line of cards has offered: stick it on a creature that the opponent now cannot answer in combat, and the math stops mattering. What separates this one from a flat evasion grant is the recurring scry trigger that fires every time the enchanted creature swings. That turns the Aura from a one-and-done combat enabler into a small engine: each attack smooths the next draw, letting you bury a land you don't need or set up the card you do. The design tension it resolves is the classic Aura risk. Putting an enchantment on a single body invites a blowout if that body dies, and you've spent a card for nothing. The scry doesn't make the creature harder to kill, but it does mean the Aura was paying you dividends every turn it lived, so even a short window of attacks recoups some of the investment. The unblockable clause is also doing quiet work as a delivery system: any combat-damage trigger, any "deals damage to a player" payoff, any voltron equipment package suddenly has a guaranteed path through. It asks you to commit to one creature and then makes that creature's connection a certainty, which is exactly the contract that the most explosive single-target strategies want to sign.
