I am not a NG player, in fact i played 0 games with NG in homecoming, but i played a lot vs NG and that counts too.
I mostly play NR these days since in is my favourite faction a it is kinda playable right now.
The NG witcher trio is very versatile and can win games for you, but it has its downside. It gives information to your opponent about the cards you have. Its very similiar to MO crones. They are very good synergy cards, but again, you know what those cards will do if they get played.
As a NR player i am very avare of danger those cards represent. I had a game with my henselt draug deck vs a guy who played ardal. That meant i had to do everything i could to avoid getting all my revenants locked and my opponent gave me all info i needed on r3 start, when he played his letho.
So i knew he had both serrit and auckes in hand so i could play around that superlock. If possible i play draug as a 3rd last card, in this case it wasnt possible bcs my opponet kept holding the duo on hand, bcs he knew i had draug, bcs i was pinging his units to 1 whole 3rd round with my units which didnt get locedk or seized. Problem was, i knew he wants to superlock me and since i had last say he had to play one of the duo before i played my draug which ment no superlock and i easily won that match. And why? Bcs he played a deck which had that trio in it. Maybe if he didnt play letho as his second r3 card, i wouldnt knew he had superlock ready and i would have played my draug as 3rd last card and lost that game...
The same goes for crones, did your opponent played a consume crone? Then expect he has 4 dmg one ready and try to play around it. Play 5point cards or cards less than 4 to deny value to him and bait it out.
The fact that those cards are strong and have good synergies mean that are in almost every deck and thats also their big weakness.
I do in fact manage to win vs most of the players who use decks which are considered ,,meta,, or ,,netdecks,, just bcs i know what they have. While most of my losses vs NG are vs decks who run unusuall cards and are considered weak. When you play vs NG you dont expect that you will need many locks or teh cards that can get locked arent very strong so i foolishly used my margarita to lock the NG melee version of trebuchet and then i lost the game, why? Bcshe had hefty helge, which is a card i have never seen being played, that guy played it at the right time and it won him the game.
I almost never use those netdecks and if i do, i always change a few cards, just because one differend card which your opponent do not expect can win you matches.
And people who call this game boring do not know anything about this game. There is a lot strategy in it, you got to plan what you wanna do based on your initial hand, you got to anticipate what is your opponent going to do and adjust the order in which you play your cards. So stop playing those netdecks and go and build your own decks. You say NG doesnt have variety? It does, not that much as other factions, but its still there, you just got to find it.
P.S I was doing my foltest deck for this faction challenge and found a card i totaly forgot that it exists, and it does wonders. I won every match vs t1 svalblod deck with it
