I took a slightly different version of this deck to FNM and managed to come away with a top 4 placing going 3-1 during the regular matches and winning the first top 8 round after which we split the prizes.
The version I ran had -4 Den Protector and -2 Thunderbreak Regent and had a full 4 Elvish Visionary, a full 4 Catacomb Sifter, Liliana, Heretical Healer
Flip, Surrak, the Hunt Caller and Languish.
Match 1 was 2-0 against esper tokens. Game 1 was won by 3 Woodland Wanderer. Game 2 I led with either Duress or Transgress the Mind and took something Important that I can't remember followed by Virulent Plague and only not drawing a real finisher prevented me from winning earlier.
Match 2 was 2-0 against R/G landfall aggro. Both games came pretty close and I dropped to near half or less than half my life fairly quickly. I managed to find enough answers and cheap creatures to stall the board until I was able to take the wins.
Match 3 was 0-2 against abzan blue. Game 1 I was stuck on 3 lands for a few turns and it was enough for my opponent to secure the win. Game 2 my opponent was mana screwed for a while but I only saw 1 Woodland Wanderer and Tasigur. I almost won with a bunch of removal, Heir of the Wilds and Catacomb Sifters but I wasn't able close out the game before my opponent stabilized and stole the win.
Match 4 was 2-0 against white weenie. Highlight of the night goes to having me play Dragonlord Kolaghan and explaining what it does to my opponent since it sees so little play and swinging only to be promptly blocked by a Dragon Hunter, the irony was palpable. Game 2 was won purely by a flipped Liliana, Defiant Necromancer
Flip, a Tasigur and an elvish visionary that I kept recurring.
In top 8 I went 2-1 against the same abzan blue player. 3 knock-down drag-out games where I managed to out-value my opponent.
MVP would go to either Heir of the Wilds or Catacomb Sifter. The 2 bodies from the sifter was a major part of winning the aggro match ups and the sifter itself drew plenty of removal to prevent me from scrying. The heirs were a major player during the abzan match ups. My opponent so worried about saving his removal for my dragons and woodland wanderers that they sided out their Silk Wrap and couldn't attack through a 2/2 deathtouch.
The cards I was least impressed with were Languish and Dragonlord Dromoka. I only saw languish once and it could have easily just been another Radiant Flames. Dromoka was in my sideboard and I just never came across a match where I felt like taking something out for her.
