Personally I like Pentecost over First Fruits. To me, getting that extra card isn't worth the risk of having a forced draw when the opponent can flip up RBD or put down Priest of Zeus.
I'd also probably drop one of the Gabe Meets Zecs and one of the Zeals to add 2x Covenant of Prayer. Then have some Trumpet Blasts in the Reserve. Another thing might be to put one of the Ram's Horns in the Reserve so CoP can grab it (to activate it on the next turn).
