Can Derevi Rule Brawl Like It Ruled EDH? 

In Edh itself isn't banned, but in formats such as Dual commander, MTGO 1v1, frech commander, etc, that heavily focused on 1v1, it is banned for the heavy relay on staxs strategies. But thank you, to point it out.

thank you for letting me know. Dumb dyslexia, ppull one on me, once I get home I'll be updating it. Really, thanks.
