Hey, I'm sorry to hear that you find it difficult to understand! There are no videos yet afaik. Let me see if I can find some time to record a video. But I'm also happy to help via text.

Basically, the goal of the game is for you to purchase, play and combine cards. In the async battle mode, you start with 5 health and need to win 10 rounds. For each round you lose, you'll lose 1 health. (In the duel mode, the damage you take is different, 25 health at the beginning 1 damage * card tier per card alive to the loser.)

You start the game with 3 gold and each card costs 3 gold. There are 5 different card tiers. Cards in higher tiers are stronger. You can get higher tiers by upgrading your shop. Which costs 4 in the beginning, reduces by 1 each round. Once you upgrade, the upgrade price changes, but still reduces by 1 each round.

If you have 3 cards, they turn into a single gold card and you get one extra card from a tier higher. You can sell cards for 1 gold each. You can also refresh the cards available to buy for 1 gold.

You can play the cards by dragging it onto the field. Once you click on ready, the battle phase starts. A random player begins with the left most card. Cards attack random cards, unless an ability is active (i.e. taunt, opportunity, etc.)

Abilities and card stats work similar to Splinterlands Battles, just that each attack also triggers a counter attack, meaning if both cards have attack, both take damage.

I hope this short explanation helps a bit.
