The best white card in MTG is Swords to Plowshares because it exiles almost any creature for just one mana, works at instant speed, and remains effective across Commander and competitive formats
I'm talking about all the fancy alternate art, borderless, fractured foil kind of cards
The player is chosen at random, but Strax's controller gets to choose which of their creatures it fights
The most promising worked as a sort of double strike variant, where a creature dealt combat damage equal to its ballistic skill during the first strike step of combat

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
Since then, smaller Cube events have been started and are more local in scope
