Three mana for 3 damage plus filtering is far below Modern rate; Faithful Mending (50) is a much cheaper graveyard-selection option.

Could be wrong if A new discard-payoff shell could make the optional rummage worth the inefficient burn spell.

Legacy's efficient burn, removal, and cantrips leave little room for a three-mana 3-damage rummage spell.

Could be wrong if A niche graveyard deck could want an instant-speed discard outlet that also targets creatures or players.

Madness Burn can use the discard outlet and reach; it compares favorably when hard-cast to Fiery Temper (58), but costs too much for broad adoption.

Could be wrong if The three-mana baseline may be too slow, and unrevealed Madness density determines whether its discard clause matters.

A flexible small removal spell that rummages has a niche in discard-focused decks, but 3 damage and no card advantage are weak at multiplayer scale.

Could be wrong if More available payoff cards or commanders for discarding could make the effect a more desirable synergy slot.

Instant-speed 3 damage to any target is strong common removal and late reach; optional rummaging adds meaningful flood protection without costing a card.

Could be wrong if Creature toughness, removal density, and draft speed are unknown; abundant large creatures could reduce its removal value.
