God, I was really hoping new Vraska wouldn't cost a ton.
Well, at least she can still kill guys on command. That's nice. And she can come down with 8 loyalty and a body to protect her, so she's going to be very tough to remove. And Menace matters on the tokens because, really, who wants to spend two creatures to block a 2/2 that'll come back next turn?
Not sure what you'll want the treasures for though. Unless you cheated her out early with a bunch of treasure already, you probably have enough mana to do whatever you want.
Main takeaway: She's really fucking beefy in terms of loyalty. 6 starting with a +2 ability that makes a dude means barring a kill spell she's sticking around. Nice to know that you'll get value off of your 6 mana.
