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
This estimates what the singles in this deck are worth to the average player on the market
