This deck works on the basis on getting the Nomi-Dragons out and from there, either use them as beatsticks or use them for exceeds.
Firstly, to prevent dead hands, there are always cards like Trade-In to toss them to draw 2 more cards, Dragon Ravine to toss them to send in either Red-Eyes Darkness Metal Dragon or Red-Eyes Wyvern so that on your next turn you can start spamming your nomi-dragons' summoning.
And of course, theres the card that many people hate, Future Fusion. Its also effective in sending multiple dragons in so that in the end phrase you can either use wyvern's effect or use birthright, call of the haunted etc to reborn the big dragons.
Then to clear your opponents' field and to toss dead cards from your hand to the graveyard, theres also the option of Phoenix Wing Wind Blast and Raigeki Break. These cards can effectively clear one card from your opponent's field as well as rid your hand of one dead card.
And because these deck is trap heavy, it doesn't hurt to tech in 2 copies of Starlight Road to stop those nasty heavy storms and torrential tributes, and the stardust dragon special summoned from the effect of starlight road is also a level 8 dragon type monster. Therefore, you can either use it to exceed or remove it for Red-Eyes Darkness Metal Dragon.
The 3 types of Nomi-Dragons used in this deck, Blue Eyes, Rabidragon and Tri-Horned Dragon are selected due to, of course, their high attack points, and also due to the fact that they are nomis which can help to bring out thunder end dragon.
Regarding the extra deck part, there are 2 fusions inside, blue eyes ultimate and F.G.D, the latter is more frequently used due to the ability to bring back Red-Eyes Darkness Metal Dragon in the end phrase with Red-Eyes Wyvern's effect. However, Blue Eyes Ultimate Dragon is teched in case there are insufficient targets to send or your already have the other Red-Eyes Card in hand.
Gustalph Max is used by overlaying 2 Red-Eyes Darkness Metal Dragon, and getting 2 of these dragons out on the field can be easily accomplished by cards such as red-eyes wyvern and call of the haunted.
Hieroglpyh Sun Dragon Overlord is also another card that can help you clear the other dead cards in hand as well as destroying cards on your opponents' field in the process. The nomis can be special summoned by using Red-Eyes Darkness Metal Dragon's effect, Birthright, Call Of The Haunted or Monster Rebonr etc, making the summoning of rank 8 exceeds highly possible.
Maestroke, Hope, Balck Corn and Roach are there in the event that 2 Red-Eyes Wyvern can be on the field. However, the focus of this deck is still on the rank 8s.
Number 15 is there to clear your opponent's specisl summoned monsters and heavens' strings is of course, for burning more damage. This is done so by using the big dragons to attack, then overlaying them for heavns' string in the main phrase 2, and using its effect which will burn your opponent for damage during their next end phrase.
Thunder End Dragon is the most fun part of the deck. It requires 2 level 8 normal monsters, so you must get out 2 nomis (you can't use stardust dragon in this case), and its effect will destroy all other monsters on the field other than itself, making it a walking dark hole.
Well thats end of my post for today, hope you guys out there like my decklist and I will be back for more next time, cya!
