Looks pretty solid in terms of a T1 MP speed deck. One change I would consider is swapping First Fruits for Feast of Trumpets for two reasons.
1) If you set aside with First Fruits, and one of your opponent's flips up Rain Becomes Dust, you're gonna lose 5 cards, including 4 random ones which could be dominants you need since FF is not an optional draw like Pentecost. If you use FoT, you can choose to do 1, meaning you only lose 2 cards (1 random) and so does everyone else except the player with RBD.
2) Feast of Trumpets is great for getting out Lost Souls at the end of the game when LS are getting scarcer. The obvious drawback is that you will be giving someone who is close to winning a chance at drawing their SoG or NJ they need to win.
Another switch I would consider is taking out Abe's Servant and adding Faithful Servant (P). He's a great character to have when so many of the "blocks" in T1 MP are SoG on Shuffler and Burial on the only LS. Having Lay Down Your Life nullifies Christian Martyr and since FS can play all of your enhancements (if you took out AStU), he's going to be very tough to block.
