Hammerfist Giant

An Earthquake stapled to a 5/4 body, except the giant pays the same toll as everyone else: it has no flying, so its own 4 damage is lethal to its 4 toughness. The activation is a one-shot fuse, not a recurring engine. Tap the giant, sweep every grounded creature and singe all players for four, and watch it topple into its own crater alongside them. That makes the card a delayed, self-immolating board wipe wearing a beater's clothing: at six mana it lands when the board is already tangled, not as an early threat but as a body you commit knowing you can cash it in for a symmetric four-point sweep the moment the ground turns dangerous. The leash is that the giant kills itself in the blast, not a faucet. You get one detonation, so the timing has to be earned: a board you have already tilted, a life total that can eat four, and a clock you no longer need the body to maintain. Flyers slip the net entirely, which means the blast clears the dirt while leaving the skies untouched. The lineage here is the symmetric-burn sweeper reframed as something you can attack with first: closer in spirit to a creature that doubles as an Earthquake you sequence on your own terms than to a card you build a board around. The body is the reason to run it; the ability is the exit it takes when the body has done its work.
