Best anti oath options for U/r Fish

[The Chosen One]

Here is my board at this moment

4 Pyroblast
3 Goblin Bombardment
3 Waterfront bouncer
2 Fire/Ice
2 Rack and Ruin
1 Viashino Heretic

Plan against oath:
-4 Grim Lavamancer
-2 Gorilla Shaman
-2 Goblin Vandal
-4 Ninja of the deep hours
+4 Pyroblast
+3 Waterfront Bouncer
+3 Goblin Bombardment
+2 Fire/Ice

This seems reasonable, although I have not tested yet, remove all creatures, I still have all 4 stifles maindeck, with now 4 Fire/Ice, and the 4 factories and the two genju for the primary kill (although I have fire/ice for the win before) Comments?
