Magic: the Gathering tweeted this tweet out approximately an hour ago from the release of this article. They announced that they will move the Banned & Restricted list announcement from next Monday to 11AM this Monday. This will be the second emergency ban, the first one being the emergency ban of Memory Jar in Standard.
As for what will be banned, this ban is most definitely a pre-emptive ban to ban some card out of Aether Revolt before too much brewing ensues. As for likely culprits, the most likely is probably Felidar Guardian out of the “Standard Splinter Twin Combo”. As I wrote about in my previous article, this combo is quite powerful. Though they could ban Saheeli, Saheeli has more uses outside of the combo than Felidar Guardian has.
What do you think are the likely culprits? Comment below!
