Secondlerdoodle, I remember these moments so fondly. What exactly happens here? The Poke Balls... go up... into the sky... and the Pokemon inside them... switch? They couldn't possibly, because you recieve them with the style of Poke Ball they were caught with. So... the two balls... switch sides? And you need to throw them into the stratosphere to achieve those ends? Even crazier than a trading machine, I'll tell you that much.
I make this joke all the time when i trade with my friends. Friend - hey remember the old ways when you sent the pokemon through the cable, didnt make much sense Me - yeah but now its more realistic, we just throw our pokeballs up in the air at the same time and BOOM its done
