Yoff beat me to the punch, this is exactly the advice I would give.I'd be less concerned about overpowered cards and more concerned about overwhelming choices when learning the game and deckbuilding though. The step method is one I have found to learn the game in the same progression as everyone else did that have been playing since it's inception.
As you play the game from Core to "Hobbit part 1", you will gain a better appreciation for how strategy in this game has evolved and some synergies and card usage you might otherwise miss. It's a lot of fun and I sincerely believe it makes you a better player and deckbuilder.
