Went 3-2 at a Prerelease yesterday. For the first four games, I played BG, and for the last I played RG.
In green, shared by both decks, Setassan Champion was pretty good. I always got a card draw off of it, but it was an immediate target for removal. Mantle of the Wolf was a huge threat, even when I forgot about it generating wolves. I had multiple Loathsome Chimera, which were pretty good. I mainboarded two Return to Natures, which did get stranded in my hand sometimes, but I usually didn't have to wait long. Mystic Repeal was mainboarded too, out of fear of the gods, but none showed up and I only got to cast it once. I got a bunch of Warbriar Blessing, and it was alright, though I faced a lot of high toughness creatures. It was good with Loathsome Chimera. I opened and played Dryad of the Ilysian Grove for a round, but it didn't do much.
In black, I opened a bunch of Minion's Return, which recurred a sacrificed creature sometimes, but otherwise didn't do much. I kept one copy in to the end, though. Mire's Grasp and Gravebreaker Lamia were all stars. I got multiple Scavenging Harpies, though it being a flier proved to be surprisingly irrelevant. The graveyard exiling was more relevant. Soulreaper of Mogis mainly was used to blank removal spells.
With red, I wanted to use Storm Herald, Dreamshaper Shaman, and The Akroan War. The first only got used as a haste creature. With the second, I got to sacrifice Warbriar Blessing and get a The Akroan War, which was neat, though my opponent conceded right after and that was my last game.
In retrospect, with all the escape creatures I encountered, I should have used the Soul Guide Lantern I got.
Overall, I enjoyed it.
