I have read this article and trying figure out how the cards are placed with different abilities and there are so many abilities that are not easy to learn. I have still not started battles because I don't know the best practices to follow and still in learning curve. You're playing well. How did you learn?
Sorry for replying to you late. I don't know how I missed it.
My advice would be to start by going to How to Play and getting familiar with some basic information related to this game because if you do not know about the basics of the card, elements, stats, etc. then you will not be able to do anything on Battlefield. By the way, after the new update of Splinterlands, now the game gives you some important information even at the time of card selection, so do not hesitate to get into Battlefield because nothing will come out without playing. Whatever I have learnt, I have learnt it by fighting battles!
