How to get back into MTG through MTGO Hi everyone.

I played a Magic a lot back during Alara Block, and have an MTGO account which I used on and off during that time and since, but none of the cards I have are really Standard legal anymore. I'm now looking to get back into Magic. My question is whether it would be better to buy one (or both) of the Dominara Planeswalker Decks to give my collection a fresh start, or to start a new account from scratch?
