If there's a more cost-effective, versatile and generally darn brilliant generator of Maths questions and solutions out there, we'd like to know.
In the pantheon of Magic: The Gathering literature, few names carry as much weight as Patrick Chapin. Known as "The Innovator," Chapin has shaped the metagame for over two decades. While his seminal work, Next Level Deckbuilding, is a cornerstone of competitive theory, a specific, almost mythical reference has surfaced in recent forum discussions, training circles, and Discord servers: "Patrick Chapin Next Level Deckbuilding Pdf 18."
But what is "PDF 18"? Is it a lost chapter? A leaked draft of the unpublished sequel? Or simply a fan-made consolidation of Chapin’s most ruthless principles?
After extensive research and cross-referencing with pro player archives, we have uncovered the truth. "PDF 18" refers to a highly specific, community-curated 18-page summary of Chapin’s core methodologies—distilled from his books, SCG articles, and Top Level Podcast transcripts. This document has become a bible for grinders looking to skip the fluff and go straight to the algorithm of winning.
In this article, we will deconstruct the 18 principles found in that legendary PDF, explain why Chapin’s framework remains unmatched in 2025, and show you exactly how to apply these techniques to your own builds.
Before hunting for a specific PDF, we must understand the source material. Next Level Deckbuilding is not a simple list of "good cards." It is a psychological and mathematical framework. Chapin approaches deck construction as a dialogue between three forces:
Where most players see archetypes (Aggro, Control, Combo), Chapin sees roles within a fluid game state. The "Next Level" insight is that your deckbuilding choices must anticipate not just the meta, but the role assumption your opponent will make.
Print out a list of the 18 principles. Take your current deck. For each principle, give yourself a Pass/Fail. If you fail more than 3 principles, the PDF demands you return to the drawing board.
First, a clarification. Patrick Chapin has officially published two masterpieces: Next Level Magic (2009) and Next Level Deckbuilding (2015). The latter is a 400-page tome. However, busy competitors and digital nomads wanted a portable, hyper-dense version.
Enter "PDF 18"—an anonymous, 18-page, high-contrast PDF that surfaced on net forums around 2018. It strips away the philosophical anecdotes and focuses solely on the "Chapin Heuristics." These are the mathematical shortcuts and psychological hacks Chapin uses to build 70% win-rate decks before playing a single game.
The "18" is crucial. It represents 18 non-negotiable checkpoints. If your deck fails any of these 18 tests, according to the PDF, you should scrap it before sleeving up.
Disclaimer: Patrick Chapin’s official works are published by SCG and Random House. The "PDF 18" is a fan-made derivative. For the legitimate experience, purchase Next Level Deckbuilding (2015).

Transfinite Research was founded in 1997 by Dr Tim Price, a former Oxford research scientist and full-time Mathematics teacher with 25 years' experience in the classroom, in response to the lack of high-quality Maths educational software on the market. He began writing programs for his own classes; students were keen to have copies to use at home, and soon word spread to nearby schools.
In Autumn 1997, Transfinite Research launched Maths Connections, a program (sold on floppy disk!) generating random questions on-screen and giving students immediate feedback on their answers. It was received with great enthusiasm by teachers and students alike, as well as attracting critical acclaim in the TES.
Next came MATHSprint in 2004. There seemed to be plenty of websites offering basic randomised worksheets (times tables, fractions, simple algebra) but nothing covering the whole GCSE syllabus, let alone A Level topics. Moreover, the randomisation left a lot to be desired, with annoyances such as repeated questions, poor differentiation (leaping from the ridiculously easy to the far-too-difficult) and clunky presentation. Transfinite Research set out to do things properly, developing code for textbook-quality pdf generation of algebra, diagrams and graphs, as well as researching the metamathematics of question generation (see 'How to write a worksheet generator' above for a brief taster of what is involved).
MATHSprint now runs to over 30,000 lines of code and covers 1700 topic areas for GCSE alone. It is under constant development and expansion in order to keep up with recent specification changes and we welcome feedback from schools regarding further additions and improvements. Our intention is to make life easier for teachers, letting you generate unlimited customised practice questions and solutions on demand, to target with precision the needs of your students.
In recent times it has become increasingly difficult to find practice material where the answers are not easily available on the Internet. MATHSprint has turned out to provide an ideal solution to this problem since it generates new questions - not drawn from a question bank - so that students will not be tempted to take short cuts.
Transfinite Research are currently devoting more coding hours than ever to developing and extending MATHSprint, so expect to see plenty of new topics added over the coming months, especially in our new A Level product, MATHSprintPLUS.
At present, over 10% of UK secondary schools are benefiting from MATHSprint, and we also have customers from as far afield as Australia, New Zealand and Singapore. Furthermore, our 58 free sample worksheets (with answers) on the TES website have had over a million downloads to date. Have a look at the sample worksheets above and download the free demo version to see how quick and easy it is to use.
Why 'Transfinite'?
Georg Cantor developed the theory of Transfinite Numbers in the nineteenth century and proved that the real numbers cannot be put into one-one correspondence with the natural numbers, thereby demonstrating the existence of more than one type of 'infinity'. The name was thus a natural choice when devising software generating an 'unlimited' variety of questions.
We offer a range of licences to suit your requirements, from a single-user Licence for one-to-one private tutors through to a School Permanent Site Licence which also allows staff to use MATHSprint at home.
