Card Duel System

Hello! Thank you very much for your interest in our plugin:
Card Duel System.

Before we continue, we would like to remind you that all of our plugins work within the environment:   
RPG Maker MZ ↔ PC Windows ↔ NWJS

If you use other platforms or devices, we cannot guarantee correct operation because unfortunately we have no way to test them. Please keep this in mind before proceeding.

Card Duel System is one of our most ambitious RPG Maker MZ plugins. It was created for developers who want to add card duels, deck building, card collection, rewards, and a complete duel workflow without rebuilding the entire game around that feature.

This system works together with Card Duel Studio, the local developer application used to create and organize the cards, decks, duelists, fields, reward pools, fusion rules, card design profiles, and runtime files used by the game.

Plugin Overview

FULL-EXPERIENCE MODE

Plugin Details: Card Duel System

Card Duel System adds a complete card collection, Deck Manager, and cinematic 3D duel system to an RPG Maker MZ project. The main goal is to let you add a card-duel mode to your game while keeping your maps, story, events, and normal RPG Maker workflow under your control.

The duel concept was inspired by the classic PlayStation 1 game "Yu-Gi-Oh! Forbidden Memories". The plugin preserves that easy-to-understand card-duel spirit while adding improvements that are important for a modern RPG Maker MZ project, including better Trap Card handling, advanced reward behavior, event integration, a dedicated Deck Manager, and many customization options.

Card Duel Studio is the developer tool used to build and maintain the duel content. It helps create cards, decks, duelists, fields, reward pools, fusion rules, automatic card design profiles, project settings, and the Random Starting Deck Pool. Players do not need Card Duel Studio while playing your final game.

You are not locked to the prepared example content. The system is built so you can create as many cards, decks, duelists, fields, reward pools, fusion rules, card graphics, card backs, card layouts, and visual design profiles as your project needs. You can keep a small card-duel mode or grow a much larger card collection according to the scope of your game.

Cards can be customized through their data and presentation: names, descriptions, artwork, type behavior, Monster values, Magic or Trap behavior, Star Guide information, design profiles, visual layout, and how they appear inside the duel and Deck Manager. The goal is to give you a flexible foundation for your own card game inside RPG Maker MZ.

Any prepared content should be understood only as a reference for learning the workflow. The real value of Card Duel System is that you can build your own card-duel experience with your own rules, graphics, style, balance, rewards, and event flow.

Features

• Cinematic 3D card duels: opens a dedicated duel scene with Life Points, hands, decks, Monster zones, support zones, battle calculation, direct attacks, deck-out loss, animated battle flow, camera movement, and RPG Maker MZ event integration.

• Create your own card content: build the cards your project needs instead of being limited to fixed sample content. You can create custom Monster, Magic, and Trap Cards with your own names, descriptions, graphics, behavior, balance, and purpose.

• Custom graphics and card design: use your own card artwork, card backs, field textures, portraits, visual profiles, and card layouts so the duel system can match the identity of your game.

• Card Duel Studio workflow: lets developers create and organize cards, decks, duelists, fields, reward pools, fusion rules, card design profiles, and runtime packages outside the RPG Maker database while still connecting everything back to RPG Maker MZ events.

• Deck Manager and Card Vault: lets players manage their saved card collection, move owned copies into the Active Deck, return cards to the Card Vault, search, filter, sort, inspect card faces, and validate deck size and copy limits before leaving the scene.

• Fusion and equipment rules: uses fusion recipes created in Card Duel Studio, supports ordered fusion logic when required, handles multi-step fusion sequences, and lets compatible equipment Magic be integrated into a valid Monster during the same card play.

• Star Guide system: adds a Rock, Paper, and Scissors advantage layer where the winning relationship can apply the configured bonus to ATK, DEF, or both during battle.

• Weighted reward pools: grants card rewards after player victory using the selected duelist reward data from Card Duel Studio, with reward chance, reward count, duplicate behavior, New badges, saved statistics, and a dedicated 3D reward reveal scene.

• RPG Maker MZ plugin commands: includes commands to start duels, open Deck Manager, add cards to the player inventory, check card possession, read last-duel data, count active deck cards, read or reset Card Duel statistics, and change input settings at runtime.

• Keyboard, gamepad and mouse support: includes default controls, dynamic prompt labels, browser Gamepad API bindings, automatic gamepad icon profiles, mouse hover selection, and touch controls when RPG Maker MZ Touch UI is enabled.

• Custom visuals, audio, and text: offers many configurable settings for duel rules, scene transitions, 3D visuals, battle animations, fusion animations, rewards, result screens, Deck Manager, card details, field display, audio, window styles, prompts, and UI text.

• Developer protection and recovery tools: supports protected Studio data for development delivery, playtest-only debug tools, contained recovery screens for duel or Deck Manager runtime errors, copyable error reports, and rollback-safe duel restart behavior when possible.

Use Examples

• Story rival battles: create an NPC duelist in Card Duel Studio, assign a deck and reward pool, then use the Start Duel plugin command from an RPG Maker MZ event when the story reaches that encounter.

• Collectible card progression: grant cards through shops, treasure chests, quests, or story rewards with Add Cards To Inventory, then let the player organize those cards in Deck Manager.

• Post-victory rewards: configure a duelist reward pool in Studio, set the reward chance and count in Start Duel, and let the reward scene reveal the cards after the player wins.

• Deck-building side content: open Deck Manager from a menu event, a guild, a card shop, or a special location so players can build an Active Deck before challenging stronger duelists.

• Event-driven results: use Victory Switch, Defeat Switch, Get Last Duel Data, and Card Duel statistics to branch RPG Maker MZ events after a duel ends.

What is a FULL EXPERIENCE MODE plugin?

At Undermax we always want you to have the best experience, and we know that a normal product description cannot show everything a complex plugin can do. Full Experience Mode is a closed and safe project prepared so you can run the plugin in its full experience before working with the complete plugin in your own project.

For a system like Card Duel System, this is especially useful because the experience is not only one feature. It includes the duel flow, Deck Manager, rewards, input support, visual presentation, and the way everything connects with RPG Maker MZ.

The content shown inside Full Experience Mode is only an example of what the system can do. Your own project can use different cards, graphics, decks, duelists, fields, designs, reward pools, fusion rules, and event flow.

Full Experience Mode plugins are only compatible with PC devices running Windows, which is the environment we work with.

Additional Information

Card Duel System is designed for RPG Maker MZ.

The plugin works with the local runtime data prepared by Card Duel Studio. The Studio does not need to remain open while the game is running, and the final player experience belongs inside your RPG Maker MZ project.

The complete editable Studio workspace is for developers only. Do not distribute the Studio workspace, editable package, password, or other private development files with the final game.

We strongly recommend testing your own card data, graphics, fields, duelists, reward pools, fusions, controls, and event branches carefully before releasing your project. Advanced customization is available so the system can be adapted to the identity and balance of your game.
