Chase Stein, Runaway

Impulse draw with a discard tax attached, and the tax is the point: you pitch a card you do not want, exile a fresh look off your deck, and get to play it any time until the end of your next turn. That timing clause is the quiet generosity of the design. Most impulse effects give you until end of turn and force an immediate decision; the extra turn lets you crack the ability on an opponent's end step, hold up mana, and still spend the card on your own turn without spilling tempo. It filters first and draws second, since the discard means you are swapping known chaff for an unknown card rather than netting cards outright. That inversion is what makes it a natural fit for graveyard payoffs, madness, and delirium: the cost feeds the bin as reliably as the exile feeds the hand, so the "downside" is doing double duty. The tap symbol is the real governor. One activation per turn cycle caps the loop, and it leaves the ability exposed to a well-timed removal spell that blanks the whole engine before it generates value. Every dead draw becomes a new look, and every discard becomes fuel for whatever wants to be discarded.
