I find the life-gain and card advantage from my two lands is worth more than another Whirler Rogue ability.

very nice deck, as a mono blue player myself this deck is very interesting, looks really good, +1, here's my own build Blugro, competitive mono blue post bfz

nice one, I have a similar deck I'm trying out:Blue Eldrazi

Will this deck still be good with out ghost fire blade after rotation?

TeamSavageMTG I've actually moved to a black eldrazi deck that is still great after rotation.

I'll post a list later.

I dont see the need for the Matter Reshaper as you only really hit land, other matter reshapers and the reaver drones so consider dropping those

Maybe consider Ghostfire Blade and Bearer of Silence as some other alternatives and additions

Georgebasto: The card Matter Reshaper finds doesn't have to go onto the field to be good. It simply replaces itself and is a form of card advantage.

I am adding Bearer of Silence b/c Kalitas is more of a sideboard card in this deck.

Ghostfire Blade will rotate by the next time I get to play at FNM after pre-release, so that's a no. It was great in Blue, but black doesn't need it.
