I mean, if you PU something earlier in the turn and then Panda afterwords, the creature that your PU generated won't be affected by Panda. 
Ummmm.... Please tell me this is a known bug.

Ok on the Nerf thread for Panda I might change my mind now..... if this is not a bug.
I was going to say Panda is fine but now....

Well I suggest everyone stay away from PvP 1 unless Panda will not effect you, then feel free. ( Ok the odds of going up against me is slim. )
Also i believe it was said that Panda was made that way so it is not a bug unless Essence is wrong and I doubt that.
