Liliana' Zombies (Oathbreaker)

This is my attempt at a Liliana the Last Hope Oathbreaker deck.
I’ve tried to build a deck that aims to capitalize on Liliana’s ultimate, by being the aggressor and establishing a board early so that I can protect her when she comes down, hopefully on turn 3.
The creature base is low to the ground as well as resilient, which allows the deck to rebuild should the board get wiped. Creatures that are self-recurring and a bit of cheap reanimation helps to keep the pressure up should you face control-decks.
The removal-suite is full of cheap, efficient and flexible spells that allow me to either clear the way for attackers, or protect Liliana from other low-to-the-ground decks, as well as directly dealing with other planeswalkers.
Some of the removal spells, namely The Elderspell and Settle the Score have the additional bonus of speeding up the process of ulting Liliana. With the help of these spells, we may be able to ult her by turn 4-5 in some cases.
This clock, combined with the numerous engines that either clog the board, or create massive card-advantage, such as Cryptbreaker allows you to almost storm off in some cases.
