Death Baron: This Zombie Lord is almost a must-have in a Zombie Tribal Deck. Granting your whole army a buff and Deathtouch is extremely powerful and in most cases very hard to deal with.
Diregraf Captain: Another Zombie Lord. Although not as powerful as the others in this deck, there isn't much reason not to run it. It mainly discourages your opponent from dropping a board wipe.
Diregraf Colossus: This card is amazing, but not worth running a playset of. Diregraf Colossus depends on your graveyard to become giant, but can work without the graveyard by spawning more zombies on top of casting your zombies.
Gravecrawler: Another staple to any Zombie deck. It will always come back no matter how many times your opponent tries to stop it, unless it gets exiled.
Lich Lord of Unx
: I only found this card recently, and I found it to be an amazing card for this deck.
Lich Lord of Unx
can be a potential win condition that rewards you for having a lot of zombies out.
Phyrexian Crusader
: It is completely personal preference to run this card. Other than this card being really good, there isn't much interactions with this card and other zombies. It is protected from a lot of removal and can wear down creatures very quickly with a combination of First Strike, Infect and potentially Deathtouch granted by Death Baron.
Prized Amalgam: This card is quite interesting, as if anything is reanimated from your graveyard, Prized Amalgam comes with it.Since this card is quite situational, only two of them are being run.
Relentless Dead: This card is the main reason I decided to build this deck. I really tried hard to put a playset into this deck, but due to my budget and its ability not always being useful, I cut it to two. Nonetheless, it is able to recur itself while also reanimating another Zombie from your graveyard, which can also bring a Prized Amalgam with it.
Undead Warchief
: I had been contemplating adding this card until I realised it was more powerful than I thought.
Undead Warchief
speeds up your game and adds a powerful buff to your zombie army.
