Reckless Impulse

The leash is the whole design. Exiling the top two of your library and granting a play window through your next turn hands you the raw count of a draw-two, but those cards vanish if you leave them unspent. That deadline is what lets a cheap refuel exist in a color the design pie insists should not simply draw cards: red trades permanence for access, seeing more of its deck and committing to those spells under a clock rather than tucking options into hand indefinitely the way blue would. The effect rewards low curves and cheap spells, where two exiled cards are almost always castable inside the window, and it quietly punishes greedy piles that would rather hold up reactive plays they cannot fire in time. It also chains well with anything that reduces spell costs or cares about spells cast, since cashing the exiled cards before they burn compounds the value. The rate reads generous until you remember the expiration; the expiration is the reason two mana of refuel is allowed in red at all, and it marks the line where impulse advantage stays distinct from true card draw. This kind of exile-and-play design has become red's standardized answer to the card-advantage problem: it gets to refill without ever holding the pieces long enough to build a controlling hand.
