Personally, I'd try to watch the games of the teams you'll will be playing against to see their style of play and then discuss pre-game what you think will work against that team, etc.
If a game goes badly their will be little time for "plays", but great teams play polo their way and force the opposition to adapt.
If you can get loads of team practice in you will be harder to break down on the court and will intuitively have an idea of where your team mates are on the court (and what plays are working/not working).
Plays are often called after a goal is scored/conceded, but never normally outright, you just have a mini talk about "more defensive", "watch the passes", "push up", etc.
