Pumpkin Bombardment

The additional cost is the whole design conversation here. Three damage to a creature for a single mana is a rate that would ordinarily be reserved for the most efficient removal in either red or black, and the hybrid pip lets any deck touching one of those colors run it. What keeps that rate from being free is the discard-or-pay-two clause: you can hand over a card from your grip, which folds the spell into the graveyard-fueling and hellbent-adjacent strategies where discarding is upside rather than tax, or you can pay the extra two mana when your hand is empty or too precious to spend. That optionality is the clever part. A pure discard cost would pigeonhole the card into aristocrats and reanimator shells; a pure two-mana surcharge would make it a plain three-drop with a discount you rarely take. Offering both lets the same card be a one-mana blowout in a deck built to throw cards away and a three-mana removal spell in a deck that is not. The ceiling stays creature-only, which is the discipline that stops the rate from spilling into face damage or planeswalker removal, keeping it honest as an answer to bodies rather than a reach spell. It is a piece of design that reads its power off the deck it lands in rather than off the mana value alone.
