Territorial Allosaurus

The whole pitch is the floor. Pay four mana and you have a 5/5 with no downside, a body green has been comfortable printing at that rate for years. The kicker is the upgrade path: spend the extra three and the creature clears the way for itself the instant it lands, fighting down whatever was holding the ground. Fight as a removal mechanism has always carried a tax green pays gladly, because it routes through a creature rather than a spell, but it also carries a structural risk: a small fighter can die to a bigger blocker, leaving you down a card. This sidesteps that entirely by attaching the fight to a 5/5. There are very few creatures it loses the exchange to, and it survives nearly everything it picks off. What makes the design honest is the timing window. The fight is locked to the enters-the-battlefield trigger and only if kicked, so this is sorcery-speed removal stapled to a creature, not a flash-in combat trick; you commit the full seven mana on your own turn and the opponent sees it coming. That puts it squarely in the late-game-payoff slot rather than the tempo slot, a curve-topper that doubles as a one-card answer once you have the mana to spare for the kicker. It demands nothing of your deck beyond lands, and rewards a board that has stalled into a grind.
