Hello! I'm not a big branded guy, so I can't say for certain whether better guides than this exist. But MasterDuelMeta recently put out a branded/bystial guide that discusses different combos, tech options, and decklists. Here it is: https://www.masterduelmeta.com/articles/guides/branded-bystial-vector#whats-new.
Hope this is along the lines of what you were looking for!
