Finally played this deck in an actual magic tournament! It did decently, but I definitely need to make some changes.
ROUND ONE
Thing in the Ice
Flip based deck. First game, I basically just got steamrolled. Second game I sideboarded in Visions of Brutality and Fumigate. I was able to slow the other deck down a bit, but still was killed before I could really start gaining/draining. Both games I kept only drawing either plains or swamps, which made it hard to actually get anything out.
ROUND TWO
Aggro green/black delirium deck. First game I got mana flooded again and couldn't really get anything out. Second game actually went extremely well. I put a Visions of Brutality on their biggest swinger, which slowed them down enough for me to have Authority of the Consuls, Cliffhaven Vampire, and Drana's Emissary all out at the same time, which let me win fairly easily. Third game was extremely close, but they managed to kill me first.
ROUND THREE
I wound up conceding halfway through the first game because draft was starting and it was going EXTREMELY slowly on both sides.
The main thing I've found is that I need more ways to slow the other side down so I can get my cards out. I think I also need more dual colored lands and some Evolving Wilds to help with getting the colors I need. I'm going to have Fumigate permanently in and sideboard Fragmentize since lots of creatures came up way more than artifacts/enchantments did.
