Compulsion

Loot for a fixed price, and the price is what dates it. Repeatable filtering was a genuine engine in the era this comes from, when graveyard payoffs and madness gave discarding a card a reason to want to discard. The first ability is the classic rummaging line: pay two mana, ditch what you don't want, draw what you might. The second clause is the escape hatch, letting you cash the permanent for one last card so it doesn't sit dead on the battlefield once the deck has stopped digging. The awkwardness is in the rate. Every activation costs , so each loop drains two mana for a card that nets you zero raw advantage; you are buying selection and graveyard fuel, not cards. That tension is exactly why it stayed a fringe enabler rather than a staple: any deck wanting to chain madness spells off a discard, or pack a graveyard for delve and threshold, had to decide whether two mana a turn was worth the churn. The loot effects that came later folded draw-and-discard into a single cheaper trigger, asking nothing further once they resolved; this one wants to be fed mana every turn it works. A clean snapshot of how Magic priced card filtering before it learned to give it away.
