Blood Feud

The interesting thing about this fight spell is that it doesn't ask your creature to participate. Most red fight cards (and the green ones that started the keyword) tie your removal to a body you control, forcing a trade or at least a creature in play. Here both targets are open: point any creature on the board at any other and let their power figures collide. That turns it from a combat trick into a controlled demolition. You can size up an opposing fatty against another opposing creature, watching an attacker eat a blocker without ever risking your own board. The cost is the rate. Six mana for a sorcery that resolves no damage on its own (the math depends entirely on what's already in play) is a steep ask, and the spell does nothing against an empty or single-creature board. It also fails the moment the math doesn't favor you: a 2/2 pointed at a 6/6 just dies and leaves the 6/6 standing. That fragility is the friction red accepts for reaching outside its color pie. Red has always struggled to kill large toughness directly, and routing damage through another creature's power is the workaround: borrow someone else's beater as the murder weapon. It is a clumsy answer at a clumsy price, but it answers a thing mono-red usually cannot.
