Chazza [1] filed a deletion request for compiz-bzr-sam [2]: This package is superfluous. It's based on a very old compiz-bzr pkgbuild that points to an unofficial compiz development branch (that hasn't seen any revisions since 2012). If users really want to use this branch they can just edit the compiz-bzr pkgbuild to point to the unofficial branch.
