Game Idea

Each player has a deck of 25/20 cards
Each round each player draws 5 cards from their deck
Cards have the following stats:
-Attack
-Defense (or HP, or whatever you want to call it)
-Special
Each round, players play one of the cards in their hand.

Let's say we have player A and player B:
Each game starts with a coin flip to see who goes first (let's say player A and let's ignore specials for the time being)
Player A plays a card with 5 attack and 2 defense
Player B plays a card with 3 attack and 4 defense

Since player A goes first, player A's card attacks player B's. Since 5 (A's attack) > 4 (B's defense), Player A's card kills player B's and removes 1 HP from player B (5-4=1)

In the next round, player B attacks and the proccess is the same. If no player dies during the 5 rounds, at the end of the 5 rounds, the player with the least amount of HP loses.

Let's go back to our game example:
Now, let's say it's player A's turn to attack:
A plays a card with 2 attack and 4 defense
B plays a card with 5 attack and 4 defense

A card attacks B, but it doesn't have enough damage to break its defense. Instead of moving to round 2, since A's attack failed, player B's card will attack. If B's attack is higher than A's defense, A loses HP, if not, both cards are removed from the table and it's B's time to attack. Even if the counter-attack succeeds, B will attack in the next round.

SO IF YOU HAVE ANY IDEA, EVEN IS EXTREMELY THE OPPOSITE OF THIS IDEA, OR DEMO FROM ANOTHER GAME, PLEASE LET ME KNOW. BUT IT MUST BE CRYPTO GAME!
