Hi yakaart and welcome to Faeria!
The matchmaking tries to match you versus other players of similar skill/level/elo. If there is noone queing at the same time with you with similar skill/level/elo, the search-algorithm will look for the second best fit, etc.
Depending on the time of day you might have a hard time running into new players, it gets especially difficult since you can make progress quite quickly in Faeria (new players get pretty good decks pretty quickly), but that is also good news for you
Try again tomorrow, and if that doesnt help, try again in the weekend, there is always a lot more activity in the weekend!
If you havent already, I recommend you check out this guide https://boards.faeria.com/t/how-to-improve-at-faeria-a-guide/438, it has helped a lot of new players, as well as Playfaeria.com.
See you ingame!
