I wouldn't worry too much about Nazareth. Plague of Frogs will be used primarily for the EC in battle and you only have 2 Searchs anyway so if they draw Naz...oh well. Naz does limit your Two Bears but again, you can still shuffle blocking ECs.
I would break down your GE like this:
Plague of Frogs

Provisions

This way, your main focus is on the true "battle winners" and you have less emphasis on the support cards (which are more "situational battle winners").
I would also drop T-Blast, Zechariah and Obadiah and add in Benaiah x2. Benaiah/Provisions is a very strong combo in T2.
