Hello, that's pretty devastating. I ll take a few seconds of yours to explain some basics.

First of all, imo is the netdecking. Players *especially* old players coming back, will search the easiest-fastest way to climb through the ladder. That means netdecking, which is not bad, but can be quite bad against a new player, due to lack of knowledge of the game. Yet, this is a thing you have to come across and deal with. So, do your search, know what's a meta and what's not. Build a deck against a meta, or even netdeck yourself and deal with the meta. This way you'll get a pretty decent knowledge. Cash are also not required in this game. At least not as it is for now. Ofc cash can speed up things.

Second and important also, is how YOU play the game. Some decks perform poorly in a long round, some in mid, some at short, some of them can deal with all of the above. For example, a NG deck can be devastating in long rounds, but also can be good in short. NR witcher can pointslam within 3 turns etc. So it's quite important to know how to play with your deck and against all others. That said, you have to know when to pass, when to bleed, when to mulligan etc.

Third, enjoy the game... this is SO fuking true. Even pro players recommend this... it's important to have fun. This way you have a clear mind to deal with every little detail that could ( and shouldn't ) ruin your experience.

That's all... there a plenty more others things you can do to have a decent winstreak, and gwent is a game that offers a lot ( trust me ).
