I'm thinking about what I want to play at the next Austin Vintage event, and Storm is hard to pass up. I've noticed that most recent Storm lists on Mtgtop8 are playing 4 Dark Petition, and splashing for Mentor. Is this pretty much accepted as stock at this point? I'm currently on 3 Petition, no Mentor.
I haven't been playing storm much, so take this with a grain of salt. I don't really like the splash for Mentor. It's not awful, but I find it awkward more often than I enjoy it. I like 4x Petition and going all-in on Tendrils (pre-board). A lot of lists seem to not run Wheel of Fortune, but I don't think that's a good thing.
