Card Duel System

For RPG Maker MZ creators

Take your RPG further

At Undermax, our goal is simple: help you build the exciting parts of your game while we handle the card-duel work that usually takes too much setup time.

Card Duel System keeps a familiar, easy-to-read card-duel spirit while giving RPG Maker MZ creators modern tools, safer project delivery, and room to expand the system as the project grows.

Creator App

Build faster in Studio

Card Duel Studio works alongside the RPG Maker MZ project you choose, keeping cards, decks, fusions, fields, duelists, rewards, and exports organized while you focus on the experience players will feel.

Built for RPG Maker MZ

Fits your workflow

Use the RPG Maker MZ flow you already know. Card Duel System connects through scenes, plugin commands, exported data, and settings while your maps, events, and story stay yours.

Card Creation

Cards ready to play

Monsters, Magic, and Traps stay clear from Studio to runtime, so each card looks good, reads fast, and has a real place in the duel.

Visual Profiles

Make it look like yours

Reusable layout profiles and image-fit tools help your whole card pool feel consistent while still giving you room to push your own style.

Arena Direction

Give duels a place

Fields combine arena texture, default selection, and ATK or DEF field modifiers, so each board can carry mood, strategy, and theme.

Recipes

Keep fusions clear

Material selectors, result cards, and relationship views help you grow fusion recipes without losing track of how everything connects.

Guardian Advantage

Star Guide stays simple

Rock, Paper, and Scissors signs add a quick advantage layer that players can read at a glance.

Encounters

Build memorable rivals

Prepare decks, assign duelists, choose fields, build reward pools, and let RPG Maker MZ events decide when the challenge begins.

Dedicated Reward Scene

Make wins feel worth it

Reward pools come from your Studio cards, so victories can grow the player collection with cards that matter in your game.

Player Experience

Give players the loop

Deck Manager, hand choices, Star Guide prompts, Magic, Traps, field view, results, and rewards connect into one smooth player loop.

Opponent Decisions

The CPU pays attention

The opponent weighs danger, hidden cards, summons, Magic, Traps, fusions, equipment, monster modes, and attack chances.

Controls

Controls feel familiar

Keyboard, gamepad, mouse, and touch support are built in, with prompt symbols that can follow the way your players prefer to play.

RPG Maker Events

Connect it your way

Start duels, open Deck Manager, grant cards, check ownership, read duel data, and adapt input directly from RPG Maker MZ events.

Customization

Shape it around your game

Rules, visuals, texts, prompts, controls, rewards, audio, Deck Manager, fields, card layouts, and event integration can be tuned without taking over the rest of your RPG Maker MZ project.

Develop Safely

Test faster, share safer

Playtest helpers speed up repeated checks, while Developer Protection can keep editable Studio data private before delivery.

Production Flow

Prepare your duel flow

Create content in Studio, test it in RPG Maker MZ, export the runtime package, and protect the editable project when you are ready.
