Well today a plan to run a team in OU when I was stopped by the most confusing restriction. Why is Raikou limited to just being a Rash nature? You can legally get any nature Raikou in Heart Gold and Soul Silver and transfer them to X and Y. I have a legal Timid Raikou that I caught with a quickball sitting in my PC, I don't see a fair reason for a restriction here. Also setting the nature to Rash makes it shiny... is only the event shiny legal? And no clue if Suicune and/or Entei are suffering the same fate.
