Today Aaron Forsythe announced changes to the banned list. These changes will take effect on June 19, 2017 in paper but will go into effect on June 14, 2017 on Magic Online. The only change this time around is that Aetherworks Marvel has been banned from Standard.
Forsythe cited the dominance of the deck as the driving force behind the decision. The choice was not made lightly as R&D understood that the recent run of bans has shaken faith in the stability of Standard and has left players fatigued. Many options were discussed including a so-called "pair ban" or introducing new cards to Standard that would otherwise not be legal such as Duress or Pithing Needle.
Forsythe also announced that given the recent deluge of bans, the next update would not take place until after Pro Tour Hour of Devastation on August 28, 2017.
