Standard is our only rotating format, and while keeping it fresh is important, we also feel that theres a more effective middle ground. Additionally, he stated that transition away from the block model (the history of which is explored below) removed some ability to build on mechanics and themes within a set. With an additional year to keep sets (and their mechanics) in Standard, Wizards can find more opportunities to build up or revitalize archetypes. The combination of both impacts, Forsythe argues, can lead to more diversity, longer-lasting archetypes, and enough competitive churn to keep players engaged. The hope is that these changes will also help create an environment where decks are more color(s) and mechanic (like Green-White Toxic or Blue-White Soldiers) and less midrange. The rest of the plan is currently undergoing iteration and will roll out as we finalize it, Forsythe concluded
