Fly

Evasion auras are the oldest trick for turning a combat step into a repeatable engine, and this one bolts venture into the dungeon onto that scaffolding. Flying is the cheapest way to help a hit connect, so the aura does double duty: it upgrades the creature's clock and it converts every unblocked swing into a dungeon advance. That reframes what a cheap combat buff is buying you. You are not paying to make a beater bigger; you are paying to make it a delivery vehicle, and the payoff banks in the dungeon rather than sitting on the board. The classic aura tension still applies: a single removal spell strips both the enchantment and the flyer carrying it, a two-for-one on tempo. But the venture rides a combat-damage trigger, not a one-shot enters-the-battlefield effect, and that distinction is the design's whole argument. Where most venture sources spend a card or a body to bank a single room, this asks nothing but connecting, then keeps asking on the following turn, and the next, until the dungeon is cleared. Kill the creature and you stop future triggers, but the rooms you have already advanced through live safely in the command zone; removal answers the engine, not the progress it has already made. The aura's value scales with how long the enchanted creature survives, which is a rare thing for a one-mana enchantment to promise.
