Discard Outlet

Permanents with activated abilities whose cost includes discarding a card from your hand, turning hand size into a renewable fuel source. Putrid Imp pitches a card for flying, Wild Mongrel and Noose Constrictor pump themselves by discarding, Lotleth Troll grows with +1/+1 counters by discarding creatures, and Anje Falkenrath loots one card at a time. These cards enable madness, reanimator setup, and hellbent plans by giving you on-demand control over when cards leave your hand. Distinct from discard.discard_payoff, which triggers off the act of discarding rather than providing the discard cost itself, and distinct from discard.opponent_discard, which forces opponents to pitch cards. Looting spells that draw-then-discard belong with card_advantage rather than here, since the discard is bundled into a one-shot draw effect rather than offered as a repeatable activated cost.
