I always love finding ways to use Black Skull Dragon and a few other fusions (especial dragon ones). Here's my stab at a Red Eyes/Black Skull Dragon Deck with a twist. I'm not worried about being tournament ready, but let me know what fixes need to be made.

Fusions

Black Skull Dragon x2 :cool:
King Dragun x2
Dark Blade the Dragon Knight x2

Ok, I have a total of 42 cards. I love fusions and Black Skull is one of my favs and always finds a place in any deck I make with Red Eyes in it. King Dragun makes summoning dragons fun and easy and Dark Blade the Dragon Knight has found a spot in my heart because he has bailed me out of trouble numerous times. I added Darm Mimic to give me some drawing power due to there flip effect. Fusion Recovery and Polys work well enough together to get fusions out quickly. Didn't want too many IFB's due to the fact that I've been stuck with multiple copies in my hand before with no Red Eyes to be found. Spell/Trap removal is covered. Have some Field control with the smashing grounds. Equips to power up monsters. Traps, to by me time. PB and COTH to get monsters back from the grave (ie Red Eyes). I think its pretty balanced with lots of attack. Speed is probably the one thing its lacking, but any suggestions would help.

divine dragon x2
dark mimic x2

lord of d. x2
mystic tomato x2
dragons mirror x2

I like the idea of Dragon's Mirror for monsters on the field, but the part of text on Dragon's Mirror about the cards listed on the fusion could cause a problem. I would probably have to run Summoned Skull, Pitch Dark Dragon and either Lord of D. or Divine Dragon in my deck plus have a way of getting them into the graveyard quickly (ala card destruction, etc) and then use Dragon's Mirror. I'm willing to drop the United and Mage and replace them with Mystic Tomato's. That would make searching for Red Eyes Black Chick and Lord of D easy. As for the Divine Dragons, I'm fine with either Lord of D's or Divine Dragons. I will consider losing one dark mimic only because I still need to be able to draw cards from my deck since Pot of Greed and Graceful have gone bye-bye for now. Thanks for the ideas.

drop all 3 king of the swamps for 3 sealed hex fusion-dark. this will spcial summon all of your fusions since they are all dark. but at the same time you won't be able to special summon outa the grave 'cause they were not fusion summoned. but its nothing that adding a second copy of each in your fusion deck wouldn't cure.

dragons mirror and fusion gate both sound like better options than polymez, but then with 3 hex fusions you could just use that open card space for a couple of cards to on the offense or defense of your stratigy.

Thats a good possiblity. It would free up 2 cards for either 2 more monsters, spell cards or traps. Probably some Wabokus or Negate attacks to insure the monsters stay on the field. The reason I usually prefer Poly or even fusion gate is because you can play them from you hand instead having to have them on the field, but I could give it a try and see how it works.

- Dark Mimic lv1 x2
+ Dekoichi the Battlechanted Locomotive x2

Same effect but better atk and def
Original deck :) 7.5/10

I completely forgot about Dekoichi, thanks, I'll definately do that.
