I haven't played on MTGO in a long time but would like to get back into playing again. I have an old account so I have a bunch of old cards (not many there even from what I can remember). I am interested in playing Standard however I don't have any newer cards on there at all so I am curious what a good pre constructed deck might be to get me back into it until I can start getting more cards again.
If Standard is your jam, Arena might be better for you however, Arena is very pay to win. I would look into Mana Traders or Card Hoarder to rent you're desired cards. This is especially beneficial if your play style changes. Rental services allow you to swap cards in a matter of seconds.
