Sideboard for my above list:
3 tormod's crypt
3 jotun grunt
4 meddling mage
1 crucible of worlds
1 sword of feast and famine
3 engineered explosives
It lets the deck change to a completely different version of UW fish. With mages to target specific cards(including swords to plowshares), grunts to eat graveyards and explosives to control the board. It seems to have something for everything. Crucible if for more long game and the sword is for green decks.
