SG, the point of the thread was for a mono gravity without upped cards.
Um.. where does it say that the point of this thread is mono gravity without upped cards?
See that word "optional" on the title? Well, I took full advantage of that option and chose upgraded cards. But my deck can be used as non-upgraded also, probably after replacing couple of creatures with Pillars. And I didn't suggest OP uses my deck, I simply showed what I have been using.
Problem with your deck is that it's very slow. Those Dragons are worst dragons in the game and I would never advice anyone to take them on a mono deck. Also your Gravity Pull works only with dragons which means you have to wait for a long time before you get any creature control going, and by that time it could be already too late.
