What's a good way to get into EDH and build a decent base of cards? I haven't played since Zendikar and that was only for a year, and before that I played a lot from 5th edition through 8th. So I have no cards anymore.

Would grabbing a pre-con and a box of Commander Legends be an ok way to start? I don't expect anything amazing, just to have a batch of stuff to build on.
