Liliana, Dreadhorde General Oathbreaker (Oathbreaker)

The aim of the deck is to win the card advantage battle against the other opponents. For that, we want to abuse Liliana's static ability that makes us draw whenever a creature we control dies.

The signature spell I chose doesn't seem to be that good at first glance, but given that Lili goes out around turn 6, our graveyard is most likely to contain zombies. So if we are close to be hellbent the turn we cast Liliana, we way don't have the fuel to start doing value out of liliana, so we have the ability to refuel our hand by taking a zombie back from our graveyard and then draw a card.

So it does make sure we will start to make value with liliana, which is really good because once Liliana get started, it goes really fast and you're gonna draw a lot of cards.

We have some aristocrats and cards that spawn a zombie on death to break a little more the symmetry of creatures dying.

We use the new Dreadhorde Invasion as a cheap tribal bitterblossom, since we aim to sacrifice the army token every turn.

Then we have some good threats that take a good advantage of the broken symmetry such as Torgaar, Famine Incarnate who is basically pay {b}{b}, draw 3, put target opponent to 10 or heal up to 10, get a 7/6, and the new lovely is Bontu that is really strong in term of body and card advantage.
