Well, here would be my list.

10.Penguin Soldier

This card allows you to return two monsters on the field to the owner's hand. This works well against strong monsters. Not only that, you can use it to your benefit as well. You can return this card and any other flip effect monsters to your hand so you can re-use their effects. Every deck should have one in case of tough situations.

9.Ceasefire

This card, though it may not be a staple in every deck, is very useful. The fact that you can deal Life Point damage to your opponent is nice, but its true beauty comes from its ability to stop flip effect monsters, such as Penguin Soldier, Fiber Jar, Cyber Jar, etc.

8.Goblin Attack Force

2300 attack for a 4 Star monster is the best I've seen,(except for a Bazoo at full power). The fact that it goes into defense mode is a good point and bad point at the same time. While the Goblin A. Force can be destroyed easily, it also provides a defense in case your opponent has something strong on the field. Staple for beatdowns, no doubt about it.

7.Change of Heart

Staple for every deck, it has always been good since it released in the Yugi Starter. Taking one of your opponent's monsters for one turn can mean everything. Not only that, you can tribute the monster you stole for an even stronger monsters, or use it on flip effect monsters and make the effects your own.

6.Magic Cylinder

Staple no doubt, this secret rare allows you to negate the attack of a monster and inflict Direct Damage equal to the attack of the monster. I've seen duels decided by this card, espicially when your opponent hastily and greedily places tons of equips on a card like Maha Vailo or Hayabusa Knight. It will redirect that monster's attack right back at him

5.Fiber Jar

A recent card that is excellent in the right situation. This card will return everything to the decks except removed cards, so you can start over again. This is great if you have used a good magic card like Raigeki, but have already used up your Magician of Faith.

4.Pot of Greed

Unmatched in the dueling environment, this card simply allows you to draw two cards. No drawbacks, and it is seldom that your opponent will attempt to counter it. Belongs in every deck.

3.Jinzo

Great monster card, it negates all traps. Although this can backfire upon yourself, you can use this if you think your opponent may try to counter with a Mirror Force. You may not think it, but this card can win duels itself if you use it correctly.

2.Mirror Force

The grand poo-bah of traps, this card will destroy all your opponents attack position monsters when he/she attempts to attack. This really helps in situations where your opponent has a horde of monsters, and he decides to finish you off by attacking them all.

1.Raigeki

Definite staple. This card can single handedly win a duel. Destroying all of your opponent's monsters can stop several strategies, some being Beatdown and Fire Princess decks. All the hard work put into getting them out flushes down the toilet. If you don't have one, get it. You will not regret having one.
