I don't think blue control runs enough black cards to reliably cast Unmask. And the free aspect isn't worth a card imo. Also, I'm no expert on storm, but I think they wouldn't want to pitch resources to cast Thoughtseize. If I had to pitch a discard spell, I would rather just cast it and pitching a bomb or ritual sounds pretty bad (it's almost like you cast Thoughtseize on both players ).
None of these applies to dredge, as you may not even have access to Thoughtseize mana and you don't care about resources - one dredger with bazaar is all you need to start.
@Smmenen Of course it's a Wizard's fault. I'm just saying that if you care about playing in the event then you try to find a solution, not just give up on it. The possibility that so many people would do the latter or not be able to find the way to join just feels strange to me. But I hope it's the case, because that means fixing this bug should revert things back to normal.
After Vintage Dailies stoppped showing in the event selection screen I had to search for a while to find a way to join. At first I wondered if some folks just can't find them, but this doesn't seem like a plausible explanation in a long run. I am interested in an answer as well.
