Well, I'm done with my shower. Let's go!
Announcer 1: It looks like today is a nice day for the first battle ever!
Announcer 2: Yep, it's... cloudy over here where we broadcast from. Whatever. Over the Card Shop this takes place in, it's fine!
Announcer 1: And it looks like Infernape Rulez, who is the challenger of this event, plays his Zubat on his bench, but leads with the deadly Seviper!
Announcer 2: Remember, fainting this guy only leaves the gift of a Bad Poison, which deals 20 damage in between turns!
Announcer 1: Yeah, you've got to status it to kill it saftly. Or have a Poison type of your own.
Announcer 2: Well, it looks like Dutch Trainer is coming up... seems to be the first time he's played, he tried to put an evolved pokemon out!
Announcer 1: We all know how you can't do THAT... but no, seems he still has 1 basic to lay down... a Slakoth!
Infernape Rulez: Seviper (active), Zubat (bench)
Dutch - Trainer: Slakoth (active)
IR, it's your turn.
EDIT: I imagined this to all take place in a Card Shop, with a shop (to buy stuff), a lounge (where you are if you're nowhere else), and a battle area (where you are now). I also imagined a system similar to the YGO anime, with the holographic stuff... yeah.
And the announcers are comic relief, with the occasional hint.
