I don't understand what people don't understand about this. We didn't get Dawn Stadium or Leafeon LvX in Great Encounters, we got them the set afterwards. Now, where the next set has the possibility of being a weird mix of these remaining 14 cards and who-knows-what-else - how is it a question...
I'll talk through my turn Set Up, Cosmic Power, name my Supporter, etc... but YES, I find it annoying when someone needs to be overly expressive through their turn. It's probably my one pet peeve whilst playing.
