Thunder Dragon

The body asymmetry is the whole pitch: a flyer that lands and clears the ground beneath it, sweeping every creature that cannot follow it into the air. Three damage to each non-flier is a one-sided board wipe with a tidy carve-out, hitting the opponent's blockers and ground stalls while leaving the Dragon, and any other evasive threat, untouched. The catch is the price. At seven mana the entry trigger has to be worth the wait, and the sweep is partial: a 3/3 ground creature dies, but bigger bodies survive to trade, and a fellow flier walks away clean. This is a Dragon built around the idea that flying is not just evasion but a parameter the card can sort the battlefield by, rewarding a board you have skewed toward the air before it arrives. It punishes go-wide ground decks hardest, the ones leaning on a swarm of small bodies that the trigger erases on contact, and it leaves a 5/5 flier behind to finish the job it started.
