Hi. I was wondering if Erika's Clefairy's attack Lunar Power can be used on the first turn? Robin

Good question, Robin.  Based on previous precedent, I would say yes.  This has presently been ruled the other way, though, so you may NOT use it first turn.  I am talking to WotC about the ruling and we'll see whether or not it will stand or be overturned.
