Crush Underfoot

Most fight or bite effects extract a price: damage echoing back to your attacker, a sorcery-speed restriction, a fixed number printed on the spell. This Giant payoff pays none of those. It deals one-sided damage scaled to a Giant's power, with no return swing to your own board, available at instant speed in response to a combat trick or whenever a target wanders into range. The conversion is what makes it sing: tie it to a creature that hits hard and two mana buys removal sized to the biggest body you control. The dependency is the cost. You must choose a Giant you control to deal the damage, so an empty board leaves the card stranded in hand. That tax is exactly what keeps a one-sided, scaling burn spell from being unfair: it rewards a tribe whose creatures already want to be large, then conscripts them into double duty as removal batteries between attacks. The design belongs to a line of damage-by-power effects that delegate the work to a permanent rather than printing the number on the spell. The instant is just the delivery mechanism; the Giant's stat line sets the ceiling. The payoff is removal that grows with your board instead of staying frozen at whatever value a card was printed to deal.
