After the duel

Turn victories into new cards.

Give each Duelist a weighted reward pool, choose how many cards can be earned, and decide whether duplicates are allowed. After an eligible victory, the game handles the chance, reveal, and collection update.

Inspect every rewardLet players understand the card before returning to the adventure.
Close the match cleanlyGive the duel a focused finish before rewards or event continuation.

Duel rules

Customize and shape every duel your way.

The core rules keep the experience familiar, while most aspects can be adjusted to fit your project.

Create different starting decks

Why stop at one when you can create several? Different starting decks help every new run feel distinct.

Customize the cards and field

By default, duels use a five-card hand, five Monster zones, and five Magic or Trap zones. Change those values and the plugin will adapt the board to your preferences.

Your next rival

A CPU that reacts to the duel.

Difficulty changes how cautious or aggressive each Duelist feels, while the CPU considers the board before making its move.

Choose the challenge

Use difficulty to shape each rival's caution, risk, and aggression.

More than simple attacks

The CPU can consider Magic, Traps, equipment, positions, and available Fusions.

Pressure with purpose

Attacks consider visible threats, Life Points, direct damage, and likely outcomes.

Adaptive controls

Using a controller? So do we!

Card Duel System recognizes supported controllers and updates its prompts in real time. Players can move between Xbox, PlayStation, Nintendo, keyboard, and mouse controls without losing their way.

Work in Studio. Play in RPG Maker MZ.

Card Duel Studio is your creative workspace. Players never need Card Duel Studio, only the finished game you build for them.

Developer Protection

Keep your editable work private.

If you need to move or share a Studio workspace, you can protect it with your own password while the finished game remains ready to play.

Before you start

A few useful answers.

What does Card Duel System work with?

Card Duel System is built for RPG Maker MZ only.

What is Card Duel Studio for?

Studio is where you create and organize the card content used by your game. It is made for the developer, so players do not need it.

How do I get started?

Install Card Duel Studio, separately acquire a valid Card Duel System license, place the licensed plugin in your project's plugins folder, enable it in a legally licensed copy of RPG Maker MZ, and follow the on-screen setup. The Microsoft Store download contains Card Duel Studio only and does not include RPG Maker MZ or the Card Duel System plugin.

Can players build and save their own deck?

Players work with a saved Card Vault and Active Deck through Deck Manager. Their collection and deck changes persist with the game save. With the optional Deck Builder Plus Expansion Pack, they can also create, name, duplicate, edit, and switch between multiple saved deck presets.

Can I create my own card designs?

Yes. Build layouts layer by layer in Design Studio or use complete finished card images. The examples show what is possible, but their artwork is not included for use in your projects.

Can I move work between projects?

Yes. Profiles can carry a complete Studio workspace, while modules let you move only the reusable content you choose.

Do I need Expansion Packs to use Card Duel System?

No. Expansion Packs are optional add-ons sold separately. Card Duel System and Studio work without them, and you can add only the extra features that fit your project.
