Despair From The Dark. The strongest level eight in terms of effect. I can drop it with a Don Zaloog effect, or Cliff The Trap Remover. If I'm hit by Card Destruction, badda-bing, badda-boom. Vampire Lord, is it? Meet your new opponent, Despair From The Dark. But if push comes to shove, there is always Call Of The Mummy.
Magical Marionette is an uber card that needs more play. Plus, with my spell-heavy deck, I'm picking off a monster every other turn.
Mystik Wok is king. In this format, monsters won't last long, so having your monster destroyed, only to have it redirected to being killed by Mystic Wok, and gaining plus whatever life points, this makes a great card. You have to be good at making timing though, or faking it.
Fox Fire is a little useful. Attack, and special summon at the end phase. Now you have a face-up defense monster that will come back if destroyed in that position.
Peten The Clown. Helps speed through the deck, but only has one timing window.
A Cat Of Ill Omen nets you a trap card when killed, so it's really useful in a deck with 6-10 traps. RFTDD, anyone?
Sangan. Really underratted. Can chain COTH on it when your creatures are about to be killed by Dark Hole, or your back-row through Heavy Storm or Moisture Creature. Free monster, I dunno why people can't see this.
Dark Dust Spirit. With Dark World Lightning, Extermination, or swordsman LV2,4,6 it's garantueed GG.
Gift Of The Martyr. More Power. Kill Sangan. What more can be said?
Pitch-Black Warwolf. The darkness equivalent to Mirage Dragon. Great in a Chaos Deck.
Skull Lair. Gren Maju Da Eiza and RFTDD just got so much better
Pole position. If saving something good, like Despair From The Dark, from Dark Hole is amazing, then having your opponent waist another resource to rid of Pole Position is God.
Back To Square One. Bounce for a discard. Dark World likes you.
Mind Crush, amazing Dark World card. Guess acard in opps. hand. D.D Warrior Lady, Assailant, heavy Storm etc. If they have nothing, then you discard a card from your hand. Wu-Lord's favourite trap card.
Fissure, the poor man's smashing ground. Fissure, the smart man's smashing Ground. I dunno about you, but paying eight bucks a common ain't my game. I wouldn't even spend that much on a holofoil piece of recycled paper. Plus, everytime you use smash, if you are a human on a budget, you'll wonder if your 8 dollar card did it's job right, and will continue to do so. But by killing off only a single creature (which is quite common in our current format), then a card costing less then a dollar could've done the exact same thing.
And some other crap cards that people get hyper-over too much. Cyber Dragon deck with only the light-hex-sealed fusion, proton-cyber dragon, and Vesargo or another fusion-material monster.
