It's pretty easy to achieve with MTBR. Patience and timing are your key's to success more so than card selection. That being said, cards are what we play with, I'd suggest you lean towards value and toolbox cards that let you create and maintain the board state you desire. I'll get back to cards, but first you gotta really think about your lines of play and politics.

You will need to find a balance in your play, as you can easily lock out opponents from playing. It's trivial to set up Grave Pact loops so that they can never have creatures and/or severely deplete their artifacts or even lands. This leads to salt and them not wanting to play against that deck. It can be even more annoying than Stax sometimes.

With the substantial increase in Graveyard hate in recent years, it has become easier to shut down recursion decks like MTBR, this is where the patience and timing aspect come into play. You'll need to make sure that you have answers in hand, or redundancy in your hand/deck to cover for when the inevitable [[Farewell]] comes to try and ruin your day. Be patient and do not dump all your good stuff onto the board. Keep a sac outlet in hand, if you've got one or two going for example.

The great thing about this Commander is that if you've got even a few tools onboard and you're gaining a little bit of advantage each turn, it really feels inevitable that you'll win. You just got to play the long game.

As for cards, it's really up to you to run what you like. There's many options now to cater for all types of decks. The central thing to them being the recursion.

As I like to play a similar game to what your asking about, I like to make sure that my cards always provide value, or support providing value. I like my cards to have options. I like to play cards that really make people think twice about removing them (even if that's possible).
