Six cards with under 3 mana, with none of the three-mana cards actually giving you a win condition. In addition, it doesn't seem like it can hit a Win Condition until turn 6 at the earliest.

Seems a solid concept, but I feel like it's trying to do too much. Should focus on one or two effects of Sacrificing, like forcing your opponent to match your sacrifice. It also seems rather slow.
Seems to me that the entire concept is flawed. You'll still be taking SOME turns, and by the time you actually get rolling with effects that might allow you to win, instead of ones that held your opponent, you'll already have lost. You can't reasonably stop your opponent from doing anything they want until turn 4 with the Train, but by then it's their SIXTH turn, they've been drawing extra cards, and they'll probably pound you to dust before you get to go again.
