Deck pages

Living deck pages.

Every deck gets a context-rich home — full list, ratios, notes, and the endboards it actually opens into, all on one page.

Endboards, shared.

Build the field state from a hand, attach it back to the deck, and share the starting hand, final field, and your notes together.

One deck. One opening hand. A saved line.

Follow a public Kewl Tune example to see how the list, the numbers, and the combo board fit together.

01 · Explore the deck

Kewl Tune Test

Will you open Kewl Tune Mix?

23.7%

Chance of drawing at least one copy in a random five-card opening hand, calculated from this deck’s current list. This counts drawing the card directly, without searches or effects.

03 · Follow the board

From starting hand to field

Open “KT Going First Basic Combo / Endboard”. Compare its saved starting hand with the final field, then use playback to step through the recorded positions.

Open example board

A community learning example, not a current-format deck recommendation. Drawing a card does not guarantee this endboard. Hand statistics use the roles and conditions you assign; new simulations require a verified free account.

The workflow

From an empty list to a saved endboard.

Build a list, check your opening hands, and save a combo board. These short demos show each step; play only the ones you need.

Step 01 · Deck builder

Start with the list builder.

Choose your cards and ratios, or import a list you already play. Keep the main, extra, and side decks together.

Build a deck
Step 02 · Deck page

Step back and review the finished list.

Review the list, add notes, and keep related combo boards attached so you can find them again.

View a deck
Step 03 · Testing

Move from theory into opening hands.

Tag starters, extenders, hand traps, and bricks. Set the conditions you want an opening hand to meet, then check how often it does.

Hand stats
Step 04 · Board builder

Turn the hand into a field state.

Play through your line manually in the board builder. Save the starting hand and the resulting field so others can follow your idea.

Build a board
Step 05 · Board page

Finish on the saved board view.

Share the board link with your group, or keep it private for your own testing. The field and notes stay together.

Built for serious sharing

Built for creators, coaches, and serious testing.

YGOPLUS is not just for building decks. It is a better way to publish them, teach them, test them, and share them with the right audience.

A saved YGOPLUS combo board
For creators

Turn videos and combo breakdowns into reusable pages.

Share unlisted deck and board pages with your public or private community, so viewers can study the list, review the combo boards, and come back later without digging through screenshots, comments, or scattered notes.

  • Use link-only unlisted decks and boards for YouTube, Discord, Patreon, or coaching groups.
  • Keep the list, boards, and combo examples attached to the same deck page.
  • Export deck and board data into Excel-friendly sheets when you need structured content.

Best for creators: Publish link-only deck and board pages that your audience can revisit on their own time.

YGOPLUS opening-hand statistics
For pros

Give your testing a clear starting point.

Compare opening-hand probabilities, review your card roles, and save the lines you want to practice. Results depend on the tags and conditions you choose; the tools do not automatically validate combo legality.

  • Use probability tools and hand stats to pressure-test consistency.
  • Keep decks, lines, and endboards in one continuous workflow.
  • Export structured deck and board data for deeper review in Excel or Sheets.

Optional Supporter membership: Higher simulation allowances and higher-precision runs help fund the site. Compare Free and Supporter.
