As my username might hint, I use zombies. Give me Dragonecro any day; I'll wreck some brains.
But I also like to mix it up. I decided to list a few other things I really like running.
[hider=My other stuff]Ban-Psychic
Ghostrick
Elemental HERO
Wicked Gods
Ancient Gear
Fiend Beatdown
Warlock Prophecy (uses Dark Eradicator Warlock in conjunction with Spellbooks & Prophecies to wreck everything)
Alien
Lightsworn
Chaos Dragon Ritual (poorly built, but easily my most original deck)
Also trying to figure out a deck that combines the effects of Magi Magi Magician Girl & Lava Golem for maximum hurt. It's not going so well ^_^;[/hider]
