League Day 2 or Mana Is Still Everything

I have no idea what my record was but I did OK, 4-2 on the day. This was the deck I ended up with, after opening M15, Fate Reforged, Khans of Tarkir and Dragons of Tarkir.

Looking back on it, I have to admit that the rare lands that I opened, forcing me to focus on the mana base and structure, was a blessing in disguise. By using the analysis from deckstats.net and keeping in everything that allowed me to generate mana, either by volume or color, the consistency of the deck helped keep me in games. I lost only one that I can think of due to color screw (hand full of white and black cards, mana of Forests and Mountains). I lost another due to flood but two games with this problem isn't a significant drawback.

In my final pack, my rare was Narset Transcendent. This was also fortunate for me: By then I was so deeply entrenched with R/G/B that going into W/U was out of the question. Caitlin opened up a Surrak Dragonclaw and ended up trying to force a four-color deck so she could play it and Liliana in the same deck. When I played her the second time, her deck didn't come together as well and I'm guessing it's because of the mana.

The other nice thing is that the initial reviews of Battle for Zendikar sealed were pretty positive. I'm still fairly dubious of the set myself in any Constructed manner but if the limited environment is good I don't begrudge people who like that their fun.
