Yeah, just make sure to do all of the training missions against the Innkeeper with all of the classes - you get gold rewards for that.
If you're having trouble building a deck that works there's no shame in looking up a basic beginners deck. The MMR system is fairly decent at lower levels (meaning you won't get matched up against people with legendary cards), so it can be quite fun playing against beginners.
The best thing to do at first is to play as one class that you like for a while to unlock that class's basic cards. If you play arena at first, you might have a bad time. Do the daily quests or push on if you're having fun.
Be warned though; I've never played a game that put me in rage mode so easily when I wasn't prepared to handle it. And I've played countless hours of Call of Duty
