How to do a card game?

Question

I want to make a game where you have an certain amount of cards in a deck, card battle, 1vs1, and you have different cards, like... Attack, defense, heal, and other things like that. You have, let's say 5 cards in your hand, and you have to play them to defeat your opponent.

I am not sure what things I may need in the making of this. Help?

Play it in real life.
Create all the cards and their unique abilities.(including texture(card pic))
Create the rule and play it with your friends.
At this point you should be able to determine the "fun level" of your game" is it fun? or boring.
Now you can design and rebuild your game, make it as fun as possible.
Then take the game rule as your game logic..turn count, loop,when to update,when to end.

I dont know html/js
But in c++, i will start making classes for player, card, etc.. After i clear all the game logic.

Btw i played yugioh, the part of the game that make it fun is.. the trap card :D
