War of the Spark is a particularly difficult set to evaluate
[a] Each player must also denote a legendary creature to be their Commander, which is able to be played at any time, without needing to draw it
If you arent able to win immediately after that, there is a good chance you are set up to win the next turn

Rosewater, Mark Subject: Crackle Off the top of my head though here are some cards that are "too powerful to bring back" that might be exciting to reprint in purple, along with what it would mean for the color's section of the pie: Mana Drain (countermagic) Fireblast (direct damage) Hymn to Tourach (discard) Rancor (trample and creature pump?) Land Tax (taxing) Land Grant (land search) Sylvan Library (deck manipulation) Dark Ritual (fast mana) The cards that really help to define the color, like the first three, seem better because their inclusion makes a lot of other cards make sense
