New player wanting to start playing

Hi everyone, I'll go directly to the point: where can I play online and see deck lists? I'm not new to TCG, but I've played mostly online for every one I've touched, so I want to start playing and see if this one is for me. I've already seen a couple of videos to learn how to play and done the tutorial through the app. Now I want to start a bit more seriously and from a quick search I didn't find an answer
