@Caharin - Lumbering Falls would be interesting but I'm not sure if the deck would have the mana to do it. I feel as if it wants to be doing something every turn (like destroying opponent's permanents) and can't really invest 5 mana into one 3/3. I'm also not sure if taplands are wanted in this deck. On the slight off chance it could matter and it could possibly slow the deck down. On the other hand manlands are always solid choices and it could possibly help the control matchup that just runs targeted removal and maybe boardwipes. Lumbering Falls would evade all of it.

I've run this deck with 4x Simic Growth Chamber and it's actually sped it up quite a bit.

Hmm I'm not sure if that's the best idea. If you've tested it and it works for you that means it's worth looking at but I'm not sure if bounce lands are viable in modern at all. The deck doesn't really need ramp I feel. If it did I would just run BoP. The bounce lands can slow us down a turn and I feel as if the deck really can't afford to stumble early (I've done verrrrrry minimal testing with the deck).

As of today is this deck still valid/worth getting?
