Realms of Power

It's this thing I came up with in my mind. Realms of Power is supposed to be a fantasy hybrid dice/trading card creature battle game.

There are six elemental realms.

Burntopia, the Fire Realm
Hydross, the Water Realm
Zephyria, the Air Realm
Understone, the Earth Realm
Freezan, the Ice Realm
Chromius, the Metal Realm

Types of Dice (most are d6's)
--------------------
World Die (a d6, or six-sided die with a symbol representing each realm, on each face)
Realm Die (also a d6. On each of a Realm Die's faces is a location in the real)
Creature Die (Creature Dice each represent a creature in RoP. Most are d6's, and certain ones are not)
Attack Die (Use when your Creature Die is attacking an enemy. It's also a d6. The Attack Die has numbers on it, and the number that the AD lands on determines how much power you put in an attack against an enemy Creature Die)
Defense Die (Use when defending against an attacking Creature Die. Like the AD, the DD has numbers on it, and unlike the AD, whatever number the DD lands on determines how much damage you can negate when defending.)

Stuff About the Dice and the Gameplay and all that.
-------------------------------------------------------------------------------------
. A Creature Die (usually a d6) has symbols on its sides representing parts of the creature's body. If you roll a Creature Die, and it lands on a body part, you can look at a body part's command list (see Creature Cards) and select an attack. The power poured into an attack is determined by what number you roll on the Attack Die. The strength poured into defending is determined by what number rolled on the Defense Die.
. If the number you roll on your Attack Die is bigger than the one the opponent rolls on his Defense Die, then his creature is defeated and sent to the RFP Area (Removed From Play).
. If the number rolled on your Defense Die is bigger than that rolled on your opponent's Attack Die, then your opponent's creature's attack is negated, and both conflicting Creature Dice (yours and your opponent's) are put back into yours/his/her hand.

Cards
-------------------------------------------------------------------------------------
Cards are another part of my made-up hybrid trading card/dice game. You can either use them to keep track of information of the realms, realm areas, and creatures seen in the dice game, or play the trading card game. Plus, like Pokemon, there are elemental advantages and disadvantages

Types of Cards
-------------------------------------------------------------------------------------
Creature Cards: They each have a picture of the creature it represents, the creature's hit points (card game only), the creature's elemental attribute, the command list for each part of a Creature Die, and the creature's side-effects in both the dice and trading card games. If a Creature Card sustains enough damage in battle, it gets sent to the Discard Pile.
Attack Cards: There are different types of Attack Cards, and they also come in six elemental attributes and have numbers to represent how much damage the card can deal to an enemy creature. If the number on an Attack Card you use is higher than that of your opponent's Defense Card (see below), then your opponent's creature card takes damage.
Defense Cards: Like the Attack Cards, they come in six elemental attributes and have numbers, only these numbers determine how much damage it can negate from an enemy Attack Card. If the opponent's Attack Card number is equal to or higher than the number on your Defense Card, then the opponent's attack is negated.
Realm Card: When you start a round of the trading card game, you can select one of six Realm Cards, and after that, pick a Location Card (see below) for the battle.
Location Cards: They represent the battlefields of the selected Realm Card. Each Location Card has a special side-effect for different creatures.

any questions and/or suggestions?

Plus, I thought up Realms of Power for the heck of it, with inspiration from Dragon Dice, Yu-Gi-Oh!, Dungeons & Dragons, and the like.
This obviously should have been posted in the Your Creations forum ...
and why not?
Anyone got ideas for this?
