I think a winning alliance would probably consist of a cycling high goal shooter, a specialist breacher, and a secondary support/high goal shooter.

In autonomous, the cycling shooter and the support/shooter will attempt to cross the outer works and score in the high goal. The breacher will attempt to cross a defense and then cross back out to give it a head start in the breaching process.

During teleop:
The cycling high goal shooter (probably the alliance captain) would run cycles between the neutral zone and the opponent's courtyard through the entire match, passing primarily through Group B and D defenses.

A specialist breacher would spend part of their match running between the neutral zone and the opponent's courtyard a total of at least 6 times in order to damage the defenses for the minimum requirement for a breach (6 because the high goal shooter will be crossing defenses as part of its cycles). Optionally, if it is capable of going under the low bar, it can cycle two more times to net extra points.

The secondary high goal shooter would start their match as the defense robot in their own courtyard, harassing enemy shooters and blocking access to undamaged defenses (note: G25 states: "A single ROBOT blocking access to a particular DEFENSE is not considered impeding the flow of the MATCH."), as well as collected missed shots of opponents and placing them in the secret passage for access by the cycling high goal shooter. Personally, I think this role is crucial to an alliance, since with a limited amount of boulders on the field, it's important to maintain control of a slight majority of boulders at all times, so that high goal shooters can continue to shoot points throughout the match.

When the specialist breacher has finished satisfying the requirements for a breach, it will switch positions with the secondary high goal shooter, which will head towards the opponent's courtyard to shoot additional high goals. The breacher will continue to play the support/defense role of the secondary shooter until end game. At higher levels of play, this transition would be made more smoothly than in the beginning of the season, as breacher bots get more experienced and efficient at damaging defenses as fast as possible.

In the end game, they will at least capture the tower and most likely 2 out of the 3 will scale the tower.
