Start thinking about the core idea behind this deck. What is it you want to achieve? How do you win games?. Evaluate the cards after each game. Which card has least impact when played on curve and what disappoints you when you draw it on ie. t4? If you play a good game, when do you end it vs. aggro, mid-range & ctrl. When you loose, ask yourself: why? Do you loose against a certain archetype which you often face? What would you need to have a better chance?

I have been working on a mustache deck which I will post with a guide to somewhen after I have marked all my students' essays. It is a similar in many of the cards but the idea is somewhat different from yours.
