(There not going to be a Roleplay of this, because doing trading cards games on roleplay is a lot harder than the real ones.)

This will be like Yu-Gi-Oh! You can come up with cards based on various characters found in Chaos Zone, whether is a character you control or any other characters that have not shown up yet. Here's how you do it:

Name: (The Characters Name)
Type: (Choose any types from the 20 types of this game to fan-made types from Chaos Zone. Total max is 2)
Level: (How powerful the character is, the total max is 10)
Special Attacks: (Move the characters have, the total number of attacks is 4)
Bio: (I think you guys know what this is, a little story about the character.)

You can do more than one at a time, just don't go crazy with it.

As for Items, it's very easy, just write down the name of it and give a description on what effects they can do, whether is good for you or bad for your opponents.

(Let just hope this goes better than my last ones.)

Example:
Name: Chase
Type: Neutral/Magic
Level: 7
Special Attacks: Mirror Dummy, Swift Run, Zap Punch, Cyber Slash
Bio: He is a Reaper that use various kind of tools to help battle his opponents.
