Grief, in my opinion, was a mistake. It should really be banned in all formats (except those where it's normal to restrict instead). In the right deck, it's a 1-drop 3/2 menace that double/triple thoughtsiezes before your opponent can drop a land into play.

But hey, they fixed that problem by banning Fury in modern, right?

As for the "no changes" B&R, I wish they were a little more willing to unban cards. For example, I wonder if Invoke Despair could come back to standard at this point (despite it rotating out soon anyway). Anyway, I guess I'm just looking forward to rotation to change up standard since it feels mostly solved (a lot of the same decks have been on top for a while now, with minor changes each new set).
