So I'm going to the SCG Open tomorrow, and I'm having trouble deciding whether or not to include Loyal Cathar in my 75. The reason being that when he shines, he really shines, but when he's bad he's really bad. The main cause for concern in going to be control decks copying him. Cause when they do that they basically get two free copies of whatever they want. (The first being Loyal Cathar, the second being whatever they want on the board) The Cathar, however, shines against the Wolf Run style decks cause you effectively have to kill it twice, so it creates a lot of favorable removal trades on my end. Thoughts?

He is really awesome but ya they get value out of their image which sucks bad. But image is bad news for us regardless..

I kept him in, and he did do really great things for me. I only went 6-3, but out of those games I mainly lost because of some jerk who dropped after round 4 caused me to lose my cool for games 2-4. I went 5-0 after that, and it really wasn't a bad experience overall. Basically dudes who call judge on everything can suck it.
