Jiwari, the Earth Aflame

The "without flying" clause is the entire personality here, and it cuts two ways. As a repeatable pinger, the activated ability scales with X but taps the body and only answers what is grounded, so a flier sails right past it: the design quietly accepts red's traditional weakness to the sky as the price of an otherwise reusable damage faucet. The Channel mode is where the card earns its slot, though, because it converts a five-mana 3/3 you never cast into a one-sided sweep priced by X. Discarding it sidesteps both the summoning-sickness tax and the tap requirement, turning a body that might rot in hand into a sweeper that torches everything on the dirt while sparing your evasive threats. That flexibility (keep it as a recurring source of damage, or pitch it for the wrath) is the real ask: the body and the discard mode want opposite gameplans, and the card is built to let you pick which one the matchup needs. The grounded-only restriction is what makes the sweeper printable at a rate that would otherwise be reckless, and it folds neatly into a long red tradition of damage-based removal that respects the air.
