Honestly, I’m not sure there are any solid, current, beginner-friendly decks around at this exact moment. There have been some excellent ones in the past, and I’m sure there will be again soon, but you’ve happened upon a moment when things are kind of in an in-between state. Sorry.
There was a major change to the cardpool just over a month ago which invalidated all the old beginner-friendly decks. Most of those players who one might hope would make new ones have instead been busy preparing for the world championship, which just finished today, so the decks they’ve been working on are (a) not that beginner-friendly and (b) mostly not published yet.
As well, you still haven’t specified what cards you have or whether you’re playing online, which makes it hard to recommend decks that you can actually build.
