Bloodfire Dwarf

The asymmetry is the whole point. For a single red mana you cash in the 1/1 body and fire off one point of damage to every creature without flying, which means your evasive attackers walk away clean while an opposing ground swarm of X/1s gets erased. That flying clause turns what reads as a symmetrical pulse into a one-sided ground sweep whenever your own board is in the air. The damage is small enough that anything with two toughness shrugs it off, so this is a scalpel for go-wide and token strategies, not a true board wipe. What makes it work is that the cost is so cheap to pay: a fragile red one-drop is rarely doing much on defense anyway, and giving it a deferred sweep means it keeps a job even after it stops attacking. It sits squarely in mono-red's long-running line of self-immolating utility creatures, the ones designed to be worth more dead than alive, where the body is just a delivery vehicle for the activated effect on the way out. The reward for building around evasion is baked into the sweep restriction itself: the more your deck leans on fliers, the more lopsided the trade becomes.
