Blastball ideas (props, devices, etc)

Is there any Blastball ideas yall can give me for my map because I have a ctf mode and a Blastball mini game in my map an I will take any ideas right now I have a scoreboard and that’s it

Have gims (sentries) watching from the stands!
Have a cool field layout (like a real soccerfield)
Have cool ads!

An Easter egg where you hit a certain part and you get a speed boost

There may be props that could help you, like cameras and other techy looking things
