Well I LOVEEEE Zombie decks but i think that pure zombie decks are not as powerful as Zombies combined with another archetype. I personally have ran a Tele-Zombie deck and loveeeee it alot. I dont want to do GoGo zombies but i would like your opinion on an archetype to combine with them comment an archetype and why you think they work best with zombies keep in mind that zombies can swarm easily. FYI: I want my zombie deck to able to XYZ AND Synchro easily not like quasar synchro but i want it to be an option. Thanks for your Help.

Hmm, well I personally don't know the Zombie archtype too well beyond the names that pop up often when the deck plays, Zombie Master, Red-Eyes, etc.
As for variants I've seen Zombies used as tech cards in some good decks, and I assume tele-Zombies are pretty good in the archtypes involved don't contradict each other.

I forgot what it was, but I remember seeing Zombie Master being used in an Xyz based deck; when/if I remember I'll post it up though.

Oni xyz or gogogo zombies probably.

Chaos Zombies, Lacooda Zombies, ZombieSworn, and more.
