I want to make a deck based around Zombie cards, but I am new to Yugi-oh and my current deck is not very useful. My Signature Cards are Bone Crusher, Patrician of Darkness, Endless Decay and Despair from the dark, and I want to have at least one of each in my deck. Here is what I have so far:

Spirit Reaper (x2)

Mezuki (x1)

Endless Decay (x2)

Zombie Master (x2)

Red-Eyes Zombie Dragon (x1)

Pyramid Turtle (x2)

Burning Skull Head (x3)

Ryu Kokki (x3)

Despair from the Dark (x3)

Paladin of the Cursed Dragon (x3)

Goblin Zombie (x3)

Call of the Mummy (x2)

Patrician of Darkness (x3)

Book of Life (x3)

Solidarity (x2)

Zombie World (x2)

Bone Crusher (x3)

I want to play it as a Swarm deck and I want something easy to use, given my lack of expertise. Thanks so much!

If you really want a swarm deck then these should be staples:

Zombie Master x3
Goblin Zombie x2 or 3
Pyramid Turtle x3
Mezuki x1
Plaguespreader x1 (synchro fodder, really can abuse him)
Tragoedia x2 or Gorz x1 or both (your choice, I'd pick gorz though)
Dark Armed Dragon x1 (not the swarm type, but aggresive and clears field)
Tour Guide x2 + Night Assailant Engine x1 (Really common plus it's an easy Rank 3 Xyz, also 2 darks for Dark Armed)
Effect Veiler x2 (just a staple in almost every deck)

Book of Life x2 (3 is cloggy IMO)
Allure of Darkness x1 (Consistency)
Pot of Duality x2 (Consistency)
Mind Control x1 (Take your opp's monster and overlay or synchro)
Monster Reborn x1 (Staple)
Dark Hole x1 (Staple)
Heavy Storm x1 (Staple)
Burial from a different Dimension x1 (Staple)
Mystical Space Typhoon x2 (Staple)

Call of the Haunted x2 (real versatile with Zombies)
Solemn Brigade (Judgment x1, Warning x2)
Bottomless Trap Hole x2 (Staple)
Compulsory Evacuation Device x1(Bounces annoying monsters or saves your own)
Torrential Tribute x2 (Blows up field and makes you go plus if used wisely)

This is actually just about my zombie deck, it swarms a LOT, letting me xyz or synchro just about every turn and overpower my opponent. If you really want to do something with those signature cards, try the Tele-Decay build, otherwise those cards really can't stand up to the meta.

Thanks for the help. I probably wont be using some of those because I am trying to go for a 100% Zombie deck, but I will use this to help me. Thanks!

If you are after a hundred percent zombie build then ur best option is probably a deck built around zombie world

I will try that, thanks.

UPDATE: I changed my deck up a bit so it now reads:

Spirit Reaper (x2)

Endless Decay (x1)

Zombie Master (x3)

Pyramid Turtle (x2)

Despair from the Dark (x3)

Call of the Mummy (x2)

Patrician of Darkness (x2)

Book of Life (x2)

Solidarity (x3)

Zombie World (x3)

Plaguespreader Zombie (x1)

Axe of Despair (x2)

Vampire Koala (x2)

Vampire's Curse (x3)

Skull Conductor (x3)

Vampire Lord (x2)

Vampire Genesis (x2)

I would really appreciate it if you want to tell me what to put in, you could tell me what to take out, and vice versa. Also, I am trying to go 100% zombie for this deck.

Thanks for everything, Guest

I am a little bit scared right now. O.O......Excuse me please, but when did I help you?

Its a trick. I used some code thing I can no longer remember. It makes it so that everybody who sees this sees their username. So for me, it says "Maxwell1070" and likewise, for Facial_Hair it says his name.

Why did you do that xD?

I felt like confusing somebody. It worked
