Ashe, Princess of Dalmasca

The attack trigger is the whole engine, and its restriction is what defines the deck it wants: dig five deep on the swing, but you only keep the artifact. Nothing else off the top ever reaches your hand, so the card is not card advantage in the abstract; it is card advantage measured entirely by how many artifacts your list runs. Build lean on them and the trigger whiffs into a random-order shuffle to the bottom; saturate the deck with cheap artifacts and every attack refuels the hand. That conditional payout is the price the 3/2 body pays for a repeatable dig on an aggressive clock. Because the look happens on the declare-attackers step, the selection resolves before blocks and before you commit to combat math, which rewards curving into it early and swinging when the board is empty rather than sitting back. The design sits in a small tradition of attack-triggered card selection, but where most of those effects filter broadly, this one narrows to a single type and turns a color that historically leans on artifacts for its ramp and equipment into a color that draws them mid-combat. The reward scales with commitment: the more the rest of the deck bends toward artifacts, the more each swing becomes a guaranteed piece of gas rather than a coin flip.
