Undefeated as of June 12, 2014.
I've played against mono-Black, Selesnya, and Orzhov.
The mono-Black deck was built around lifegain with Sanguine Bond. I never got off the massive card draw combo with this deck due to all of the removal at black's disposal. Once my opponent realized that I was mainboarding 4 Notion Thief, he realized he had to remove first chance he could. However, I won 2/2 games. When card draw isn't viable, Master of the Feast still shines. I would play Master of the Feast and Dictate of Kruphix to keep my counter spells and removal available for anything that targeted my Master of Feast. Sideboard went to Bile Blight and Dispel. I took out 2x King Macar, the Gold-Cursed, 2x Phenax, the God of Deception and 1x Elixir of Immortality. Game one was close, game two easy.
Selesnya was my hardest game. I won 2/3, lost the first game mainly because of poor choices on my part. Game 1 I took his Karametra, God of the Harvests on turn 1 with Thoughtseize and I took his Vastwood Hydra with Brain Maggot. I still allowed him to get his ramp creatures out and go monstrous with a Fleecemane Lion on turn 4. It was completely my fault. Sideboard was two more Thoughtseize for 2x King Macar. Game 2 I milled him out with 5x packrats + mutavault + Phenax (active) for 37 cards. 3rd game was all about my Master of the Feast. I am starting to love that card.
The Orzhov deck was just a test deck built around life gain, and I went 5/5. Game 1 I was able to get off my combos to eventually be drawing 4 cards on my turn and 1 card on opponents turn every round. This was thanks to Master of the Feast, Dictate of Kruphix and Notion Thief. It gave me plenty of cards to pitch to packrats, and when I popped my elixir, he scooped. Game 2 was 2 Master of the Feasts in the air for a two turn clock. His life gain was good, but just a little too slow thanks to my removal with Brain Maggot and Thoughtseize. No sideboard on this game.
