While it may be a little too effective in rainbow stalls, this card in itself I don't believe to be overpowered. Using Air and Light one normally thinks of, or at least should think of Blessed Pegasi, a strategy that aims at diving right at the HP of the enemy. It's not exactly the best deck to merge with a stall.
I will however consider raising the cost of
Peace to
Peace as this card would probably find itself a comfortable place with Novae as it is right now.
If you still think that it's overpowered, please post the kind of deck that would maximize the efficiency of this card and ultimately prove that this card is overpowered.
