In this book, Will Jonathan does an excellent job of synthesising many of the key facets of sports psychology into a Magic: The Gathering focus. I've read numerous sports, gambling, and trading psychology books, so many of the concepts in this book were familiar to me, but for somebody without any sports psychology background, this book is a great starting point.
The author tackles many areas of the game, from mindset, to developing confidence, dealing with tilt, implementing habits and regimes, playing with focus, motivation, and many others. He breaks these down into digestible, stand-alone chapters so you can read the book piecemeal and still gain many benefits. This is a reference manual that will appeal to people at any level of the game, from rank amateur to professional. In fact you don't even need to play Magic to gain the benefits of this book, as much of the information contained is easily transferable to other hobbies, sports, and life in general.
I give this book 4 stars and not 5, purely due to some gripes I have with the physical quality of the book itself as well as some editing errors. The book is a nice A4 size and the cover looks great, but the print and paper quality is inferior. I bought my copy from Amazon and was forced to contact them due to the fact that there were ink streaks throughout the book (primarily on the right hand pages) and many of the pages were blurry and difficult to read as a result. Amazon sent me another copy, and the second copy had exactly the same problem as the first, which makes me think the author has decided on a cheap printing option? Basically the book has the quality of something that has been self-published or self-produced, so given the price tag and the fact that it was sold through Amazon I was somewhat disappointed.
The editing errors range from minor (such as when the author says that he: "returned in 2007 and played for a couple more years before I took a long, 6 year break from the game. I returned in 2013..." which clearly doesn't make mathematical sense), to the more significant issues in the 'Implementing Habits and Routines' chapter. In this chapter, the author details a 'Pre-match' and 'Mid-Match' routine, which if followed by an unknowing player, would lead to a judge call and a warning. The author recommends the steps:
1) mash shuffle + breathing exercise
2) Pile shuffle + affirmation
3) Present deck to opponent
This is in violation of the rules as pile shuffling isn't 'shuffling' at all , but merely used to count the cards in the deck and can be viewed as a means to order the cards, so if you follow the recommended steps you would be presenting a non-randomised deck to your opponent and be in violation of the rules. This mistake is repeated in the Mid-Match Routine section which makes me believe that the author is unaware of the rules in this instance. The correct sequence is to reverse steps 1 and 2, so that you pile shuffle first, then mash shuffle, then present to your opponent.
(It's also worth pointing out that the rules regarding pile shuffling were updated in 2016. The author's disclaimer at the start of the book says that the information contained was correct as far as he knew as of December 2017).
In summary, this is a great book for gaining a mental edge in Magic: The Gathering, and contains exercises and practises that are applicable not only to magic but to other sports as well. It's a shame that the print quality of the book wasn't better, and that the book contains editing errors. Sans these problems, this book would be a clear 5 stars, and would be the definitive guide to the mental game of magic without any requirement for addendum or updating. Don't let those minor negatives hold you back however, if you are interested in winning more, and more importantly, ENJOYING the game more and becoming happier in the process, this book is a must read.
