Mulligan for
Shard of the Spire or
Yisha, the Equalizer. You can absolutely win without them, but they're kinda the point and make everything a lot sweeter.
No main deck removal. A mistake? Feels like it sometimes, but not as often as you'd think.
Pristine Light is so good in the Market that I'm tempted to main some copies, but I don't think I have time to durdle like that and my 3 slot is so crowded.
I'll probably try this in Ranked, because I'm a masochist, but this is a Gauntlet deck, for sure. A fun time waster, does neat things, won't win any tournaments.
