The most effective pattern for an architecture team is as a part-time enabling team (if one is needed at all). The team being part-time is important: it emphasizes that many decisions should be taken by implementing teams rather than left to the architecture team. Some organizations compose a virtual team from members of other teams. This virtual team meets regularly to discuss and evolve the architecture aspects of the systems. This is akin to the chapter or guild terminology used by Spotify (see Chapter 4).
