Grand Line Profits
René Charles Presents
Stop Collecting Cards. Start Trading Margins.
The Operator’s Blueprint for the One Piece TCG.
The definitive, high-velocity blueprint for scaling a professional One Piece TCG trading operation. Deploy capital efficiently, pre-screen raw cards like a lab technician, and dominate both digital markets and live showcases.
“This course is built strictly for operators. No fluff, no collection-showoffs. Just pure sourcing mechanics, margin optimization, and live show dominance strategies.”
The Operating Framework
Built for High-Yield Card Flipping
Traditional card advice tells you to buy cards you love and hold them. We teach you how to treat cards like inventory, optimize cash-flow velocity, and build a sustainable business.
-
Market Intelligence
Learn the “Compass Method” to predict card prices based on Bandai’s print cycles, tournament performance, and player-vs-collector demand curves. Never get caught holding a falling knife.
-
Sourcing & Pre-Screening
Spot microscopic flaws before buying raw cards. Master centering geometry and edge audits so you know which raw cards are worth grading before you pay for them.
-
Live Show Domination
Our unfair advantage. Learn René’s proprietary merchandising, booth layouts, and live trade-in negotiation scripts we use to move more cards at physical card shows.
This Is the Floor
Grand Line Profits is run by the operator of the Miami Local Card Show — the monthly Pokémon & One Piece TCG show in Little Haiti, Miami.

Frequently Asked Questions
Who is this course built for?
This course is built strictly for operators, dealers, and serious card flippers who want to treat the One Piece TCG as a high-yield business. It is not a collection showoff or a basic beginner guide. We focus entirely on sourcing margins, capital velocity, grading pre-screening, and live card show merchandising.
What is the Syndicate program?
The Syndicate is an application-only, 90-day high-ticket program limited to 5 operators. It includes direct 1-on-1 WhatsApp access to René, personal pre-screening audits of your card submissions, exclusive off-market local collections, and prime partner placements inside the Miami Local Card Show.
How do I get my downloadable study guides?
Once you enroll, all 36 lesson study guide PDFs are instantly available for download inside your CourseCreator360 member dashboard, positioned directly beneath each corresponding video lesson.
Do I need prior TCG trading experience?
You need to understand the basics of the One Piece TCG card market and have some capital ready to deploy. The course is not a beginner’s guide to what cards are — it assumes you know the game and are ready to treat it as a business.
Is there a refund policy?
Due to the digital nature of this product and the immediate access to all course materials, we do not offer refunds. If you have questions about course content before enrolling, reach out to us at miamicardshow.org.
