There are two decks i use Dragunity and twilight dragons (I LOVE DRAGONS!!!)
My trump card in my Dragunity deck is: Dragunity arma leyvaten (ATK/2600 DEF/1200, I special summon it with dragunity aklys (ATK/1000 DEF/ 800), his effect allows me to special summon Dragunity arma leyvaten, and dragunity aklys is automatically equipped to him (ATK/3600 DEF/2000), Dragunity arma leyvaten's effect allows me to equipped another dragunity dragon-type monster from the graveyard to him, i normally use Dragunity Arma Mysletainn (ATK/2100 DEF/1500), so that's a whopping 5700 attack and 3500 defense. and that's all in one turn!!!
Also dragunity aklys effect allows me to destroy a card on the field when the card it is equipped to destroyed. so if you manage to destroy it with a monster i can also destroy it. But i guess the weakness is spells or trap cards, that is why i also added a Jinzo to the deck.
The trump cards in my dragon deck are: 5-headed Dragon, Cyber End Dragon, Meteor B. Dragon, stardust dragon, shooting star dragon, red dragon archfiend, red nova dragon, the rest of the 5D's, Queen dragun djinn, Rainbow dark dragon, Felgrand dragon and galaxy eyes photon dragon and neo-galaxy eyes photon dragon. I know you might (or not) think that's a long list and that i might not be able to summon them, but i use cards like kaibaman to summon blue eyes and photon sanctuary to summon galaxy eyes.
i am also considering in making a malific deck.
Please click on one of the dragons above, you don't want them to die, do you?
