Just started playing and I love it. - eviltoast

I started playing this a week ago, I’ve already purchased 6 decks. I started playing MTG at the tail end of 4th edition but the direction hasbro too mtg really turned me off - since discovering this, I really feel like this will fill my tcg void.

You all have any tips / tricks? Good wats to build a collection? How to get started in constructed?

Thanks!
