I was reading MaRo's
Common Courtesy and wanted to make a red instant that pumps power and either grants first strike or haste. A Lightning Reflexes or Reckless Charge type effect.
One of my favorite mechanics is cycling, and I love the Onslaught cycling cards that granted minor effects. I wanted to explore that design space a little further.
