Phantasmal Images for the Geist(or tribute to hunger if that takes your fancy), Spot removal+Snapcasters for everything else. I've only played against it twice but from the looks of it, it seems pretty straight forward/easy for U/B Draw-go.
Not sure I understand what you're trying to say here. They aren't cutting Dungrove for Thruns. They are running both. If all you are siding for is Thrun those Dungroves are going to kill you. Against us they side out Beast Within and Acidic Slime for Thruns.
I should have been more clear, I don't really mean from sideboard to mainboard, I mean that the increasing trend in WRG decks is fewer Thruns in the 75 with more dungrove Elders. If this happens at my LGS I will probably play a Life's Finale in the board, but at the moment everyone is running 1/2 dungrove and more Thruns in the 75 so Phantasmal Image is fine for me.
It depends on the situation there is no concrete answer to this.
^This, however in control match ups I find myself rarely ever playing my finishers and playing a more passive controlling game, winning with my mainboard Drownyards (+2 more in side for 29land with 4drownyards).
Works wonders.
I prefer Wurmcoils as they are a lot harder for aggro/midrange decks to deal with. Batterskull has its place in equipment-esque decks like Puresteel etc. I'd just stick to Wurmcoil Engine in U/B
This is more of a meta call than anything, I'd only run life's finale if I was expecting to come up against of a lot of WRG. And more importantly if people are running less thruns to run more Dungroves. With the amount of Thrun's that WRG are running I'd just stick to the Phantasmal Images in the side.
I don't agree with the use of creature buff enchantments on anything except Hexproof creatures. It is an easy way to 2 for 1 yourself. Personally I'd run without Angelic Destiny and especially not Spectral Flight.
