Very nice simple design. Awesome card yet very suitable for common.

Thanks. I can't take full credit for this card though. It is based on both a card that Jonathon Loucks submitted during the GDS2 elimination rounds and the Feedback he got on that card.

Some of the first cards I posted in this non-set were inspired by his submission and my trying to "Fix" his Illuminate mechanic. I guess the basic concept of his submission struck a chord as I keep coming back and creating new cards for both sides - Light and Dark. So Kudos and Respect to you Jonathon, I hope you take my riffs on your cards as they are intended.

There is a card in AVR that does 1 less damage for the same mana cost so this MAY be overpowered.

Nah, this was originally designed to form a new cycle with Lightning Bolt and Leaf Arrow. If green can have conditional 3 point burn for 1 at common then I figure white can too.
I think WotC were just a bit too conservative with Righteous Blow.

I also designed the same card in Crash Headlong. I couldn't tell you if you beat me to the punch in GDS2 or not. Magic 20XX was designed right around then. Guess it was in the air. I'm pretty sure I was thinking about Leaf Arrow at the time as well.

The removal in Avacyn Restored is in really, really short supply. I infer that white lightning bolt would usually be fine, but that white shock is perfectly printable.
