On June 18th, the EDH council announced a new round of bannings. Their bannings are more like guidelines (unless you're playing a DCI sanctioned event) for your local play group. Most groups abide by them though.

Banned as General: Rofellos, Llanowar Emissary

[draft]Rofellos, Llanowar Emissary[/draft]

Banned from Decks: Tolarian Academy, Channel and Staff of Domination

[draft]Tolarian Academy

Channel

Staff of Domination[/draft]

Note that Rofellos can still be played in your deck as one of the 99 non-general cards.
