Thanks, I have a few playsets of Evolving Wilds and Terramorphic Expanse is just as cheap. I could see deck thinning mattering a great bit more when the whole idea behind the deck is to keep drawing gas for lethal.I would try 4x Evolving Wilds and Teramorphic and run more basics. They are better than Sulfur Falls, and the thinning of the deck is actually important.
Don't just watch games, goldfish whenever you can. If you have never played a complicated combo deck before- I'm talking in the vein of ProsBloom, Heartbeat and ANT and not Twin or Scapeshift- you are going to need a lot of practice to play the deck. Its not easy- even Jon fucking Finkle, the best player ever, sometimes has issues with it-, and to most people it doesn't even feel like Magic, but it is a rewarding experience.
Remember when goldfishing to try 6, 5, and 4 card hands as well- if your only practicing 7 card hands, any Mulligan is going to kill you. Also keep hands and discard the best card from it to simulate being Thoughtsiezed, ect
I've been using Mtgvault's "Draw Sample Hand" feature to try to formulate my lines of play. I've been simulating a Thoughtseize and a single mulligan from time to time, but I haven't gone lower yet. I also haven't played it out to the end of my combo. Doing so may have lead me to find that enough lands in one place will stop the combo short of lethal, especially in my original land configuration.
There's a few guys at the shop who play Modern elsewhere so I'll playtest with them when possible. This deck may be budget but I'm definitely hearing that it's nothing but difficult to play. I'm already ordering cards and looking forward to the challenge.
Thank you for the advice.
