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?
This is my current Boros deck I’m excited for - 12 adventure creatures with removal means I have both a very threat-dense and interaction-dense deck, which means I have room for cards that would normally live in the sideboard, like the Invasion, Nahiri, and Emrakul: https://www.mtggoldfish.com/deck/5823058#paper
