A way to buy more cards

So I bought the complete collection and want to support the game more while needing more cards for multiple decks. Issue is i dont need stl files and buying every deck again like I want to is a bit steep at 30 per deck. If they could sell card decks (not singles) only at 15 bucks or so that would be great and I could buy all the decks again to support the devs

Now the downside to this would be new people getting confused and probably being better off with the stl decks but accidentally buying the card only decks if they got confused. But i would like a way to suppoet the game and make multiple decks without spending another 300+ dollars. ​
