Burning Anger

The Aura that turns a creature's power stat into a firing pin. The granted ability deals damage equal to the enchanted creature's power to any target, so the math scales with the body: strap it onto a fatty and you have a repeatable cannon in the Spikeshot Elder or Bloodshot Cyclops mold, pinging small creatures and planeswalkers one turn and dumping the whole total at a face the next. The timing is friendlier than five mana suggests. There is no haste requirement on the granted ability, so as long as the creature has been under your control since the start of the turn and is untapped, a fresh Aura on an established beater comes online at once. The tap cost sets up a tension between combat and reach: normally the creature must choose between swinging and shooting, but vigilance or any untap effect collapses that choice, letting one body attack and fire on the same turn. And the fragility is the standing tax on the whole buff-Aura line. Sinking five mana and a card into a permanent that dies to any single removal spell hands the opponent a two-for-one, and the more power you have piled onto the enchanted body, the more that one answer costs you. The payoff scales with the creature's size; so does the downside of losing it. The design lives entirely in that trade between a growing threat and a single point of failure.
