Silent Arbiter and Brimaz actually work well together. Normally, when Silent Arbiter is on the battlefield, no more than one creature can attack or block.

Now Brimaz’s little friend attacks alongside Brimaz, as a result of his triggered ability. This works because Silent Arbiter sets up an attacking (or blocking) restriction. It merely prevents attacks from being declared by more than one creature. He is not able to prevent Brimaz from triggering. Although two creatures will be attacking, only one of them “attacked.” However, Silent Arbiter’s effect will still be active and your opponent will only be able to block one of them!
