Playing against Half Bloods, I almost never lose with a slightly upgraded mod of this deck (3x SoGs only). I only have one Fahrenheit in the deck and if i play it after my fire quata has built up past 40 or so, I only have to use one fire bolt most of the time and that's just to get EM at the end... Plus, you can use most of the firebolts defensively if you're feeling confident. This deck has the perfect balance of permanent killers, shields, and the ability to use the opponent's deck against them. Only use antimatter against high damage opponents or if you really need healing; they're the best part of this deck so use them wisely. Oh, and don't try it against anything lower than a T50 though, the win percentage decreases dramatically... you need to play against the heavy hitters. Here's my deck code:
Mark of Entropy: 4vn 4vn 4vn 4vn 4vn 4vn 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f4 5f4 5f4 5f4 5f4 5f4 5f5 5f5 5f5 5f6 5f6 5f6 5f6 5f6 5f7 5gi 5gi 5gi 5gi 5gi 5gi 5gi 5gi 5gi 5gi 6rn 6rn 6rn 8pj
Edit: Ok I was on a huge winning streak and probability is paying me back now... still, this is an excellent deck for beating half-bloods. It's the most fun to play of all decks I've built (yeah, I'm a noob, but a dedicated noob). It takes strategy as well as luck. How you decide to play your cards seems to decide the game more often than not. Thanks to BluePriest for the deck seed.
