I mostly play Pioneer and am very excited for some of the new Adventures. I've already brewed up a Boros Adventures midrange deck that I think could be a contender, and I definitely wasn't to try the black mythic Virtue in Rakdos. Beseech the Mirror also looks like it will affect multiple formats, up to legacy! What cards are everyone else excited for?
I have a good handful of “sword of _” and white equipment cards so I’m thinking about building a Kellan commander deck where I can turn 2 search for any equipment is what I’m considering now but I’m not quite sure. I also wonder if Hearth Elemental is the new Gurmag Angler but I don’t know if that’ll be as good as I’d like.
