2v1 Who Do I Help?

Groups of three players
The defending team nominate a goalkeeper
On the playmakers call, the two defenders dribble and pass to two of the attackers
Immediately we have two 1v1 situations.
The attacker not receiving a pass must quickly make a decision of who to support
The spare attacking now makes a supporting run to make a 2v1 situation with one of his team-mate
Progression
if one game is completed but the other ball is still in play, all players can support this ball
Magic Ball from playmakers to continue that phase once balls are finished
