In an unannounced Banned List update, Fall from Favor has been banned in Pauper effective today, January 14. As cited in the article, Fall from Favor serves as both a removal spell and a source of card advantage. The goal of this ban is to increase the potential of aggressive strategies.
The announcement also details how both Tron and Monarch are issues in Pauper but that no additional action will be taken until after the January 23 Pauper Super PTQ on Magic Online. The ban of Fall from Favor immediately changes the landscape of competitive Pauper but whether it is enough to fully diversify the metagame remains to be seen.
