Warbriar Blessing

Green's fight spells have always paid for their card disadvantage with tempo: you spend a card and some mana to point one of your creatures at one of theirs and blow it up in a single exchange. This one reframes that trade as a permanent instead of a one-shot. Because the fight is stapled to an Aura, you keep the enchantment on the battlefield after the removal resolves, and the +0/+2 does double duty: it pads the toughness of the creature going into the fight so it survives the exchange more often, and it lingers afterward as a small buff. The "up to one target" clause is the quiet flexibility that separates it from a naked fight spell: with no legal target, or no target you want to trade with, it still resolves as a modest aura rather than fizzling. Routing removal through an Aura carries the usual cost, though: it demands you already control a creature worth enchanting, and it hands a two-for-one to any instant-speed answer that kills your creature in response to the trigger. The card lives in that exposure, trading the resilience of a permanent-based fight for a vulnerability window between the Aura entering and its trigger resolving, when a single well-timed removal spell turns your removal into their two-for-one.
