Selection of Star player and Captain can change the entire game as Star player gets 2 x points and Captain 1.5 x points, so choose it wisely.
Select at-least one Raider for Star player or Captain as they usually score more points in a match.
Avoid selecting Defenders as Star player. However you can select good Defenders as captain.
If both the team has best Raiders then select Attackers as the Star and Captain Players.
Never select the Star and Captain player from the same team as they chances are very less that both the players are performing well from the same team.
For player who you are not sure of how they will perform in the match , mark them as Z-Factor as their points will be reduced to half the points they score in actual match.
