Chapin expanded on the concept of the "Metagame Clock," a cycle showing how archetypes relate to one another.
The Principle: Decks generally beat those clockwise from them and lose to those counter-clockwise (though modern Magic design has blurred these lines). Understanding where your deck sits on this clock helps you sideboard correctly.
Most players build from their win condition backward. Chapin builds from their mana forward.

Let’s assume you’ve absorbed the lessons of this mythical document. How would you build a winning deck in today’s Modern or Pioneer?
Step 1 – Identify your 9 core cards (the 18).
Example: In Modern Rakdos Scam, your core is 4 Grief, 4 Fury, 4 Feign Death effects, 2 Thoughtseize, 2 Undying Malice, and 2 Not Dead After All. That’s 18 cards.
Step 2 – Calculate your 18% removal threshold.
For 36 spells, you need 6-7 removal pieces. You add 4 Lightning Bolt, 2 Terminate. Chapin expanded on the concept of the "Metagame
Step 3 – Determine the 18th land.
Average CMC is 2.2 (excluding free spells). You start at 20 lands, then add one for every 18 cards above 2.5 CMC – none apply. So you run 20 lands, not 24. That frees up four slots for flex.
Step 4 – Flex slots (repeat the 18-card test for sideboard).
You now have 18 sideboard slots (15 in reality, but Chapin argues you should think in terms of 18 possible swaps including transformational moves). You build a mirror 18 plan: 6 graveyard hate, 6 artifact/enchantment removal, 6 anti-aggro tools.
The result? A tight, efficient deck that never stumbles on mana, always draws the right interaction, and can change roles post-board. The Principle: Decks generally beat those clockwise from
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 A leaked draft of the unpublished sequel?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.
