Not an expert, but I feel I'm going to start tinkering with @Shaman-Ben's list. I'm undecided on what I'm going to do completely. The thing I find about the deck, it's not a negative, is I'm hesitant on going all in as much as this list appears to want to do. I think that's a bit against my play style, so I think I need to tweak it there. My win rate with the deck is not good in my limited experience, but I'm going to chalk that up due to variance and misplays (not taking anything away from my opponents - I've played some extremely good players). I think my number one misplay is somehow managing to forget to put down Leyline turn 0 on ocassion. That cost me a round yesterday (Not guaranteed, but way higher percentage).
What I found about this list and feel free to chime in Ben. I talked to him a bit about this. I noticed a few things.
I have a tendency to draw too many lands or not enough. I end up with a lot of dead hands, mulliganing to oblivion. Obviously, there is variance that probably has more to do with it, but something I noticed yesterday. I never saw a lot of the draw cards or the tutors yesterday, so I was out of luck a lot.
I also end up a good percentage of the time always being one turn too late. Like one mana short (or a couple) to activate one of the combos and getting killed on the swing back. I get that it will happen, but I think that may make me want to drop down to try 3 Workshops and see how that goes.
I also would to see a little more game against people turning creatures sideways. I got knocked around a bit with this yesterday and had no answers quite a few times. I'm not quite sure what I want to do about this (if anything), but I'm going to try to look into it.
