Its way too early to tell what kind of decks you can actually play in the format, but why would I let that stop me? Therefore, this little idea:
This is going to be quite slow, because we are trying to ramp to the new Ulamog, which costs 10. There’s some other cards on the way, which might be good, but Ulamog is our goal. We have plenty of (quite slow) ramp and this deck will probably lose most of the time simply because its wasting its time trying to get more lands into play.
There aren’t many early drops, so any fast deck is going to run all over you. There isn’t much business, so any control deck will just shut you out of the game. But there is Ulamog and it rocks. Even though I don’t really like the new art.
Getting some roadblocks, like the new 1/1 Eldrazi Scions, would probably help. I there’s a card that produces them cheaply enough, it should definitely go into this deck.
All in all, this deck is just the Tammiest thing I could come up with. It shouldn’t be taken very seriously.
