CARD BATTLE SYSTEM

So, here's a battle system script I would like made for a game I'm making.
The system has it so you have 3 Card types. Here they are:

Attack Cards
With these cards, you have three slots for cards to use. For example, say you have three cards set called Low Strike, which does 5 to 8 points of damage, Medium Strike, which does 8 to 12 points of damage, and Heavy Strike, which does 14 to 17 points of damage. In battle, when you choose the Attack Cards option, it randomly selects one of these, or another, fourth card, called Miss, which, misses. It does damage accordingly.

Skill Cards
With these cards, you have 5 slots. They work the same as Attack Cards, the only difference is that they have elements, and are usually more powerful. HOWEVER, using a Skill Card skips that character's next turn. Some might even have some other side effects, like inflicting damage.

Protect Cards
These cards can used to block attacks, heal, and buff characters. They don't skip your next turn like Skill Cards, and can be used once per turn. You can set five of these cards.

In the end, its a hard task. Oh, and items cannot be used in battle. Just a side note. Thanks, to those who can do this!
