Disaster Dragon with a bit of a twist

Hi guys, this is the deck im currently using in DN, well my favorite one. Ive been a fan of the dragon theme decks since the Lvl up series but lately with the rabbits/evolzar laggia decks and gadgets/chaos decks i have been suffering a lot.
Anyway any tip or suggestion is welcomed.


Monsters: 19

2 Thunder King Rai-Oh
3 Koa´ki Meiru Drago
2 Red-Eyes Darkness Metal Dragon
3 Red-Eyes Wyvern
3 Masked Dragon
1 Exploder Dragon
2 Delta Flyer
1 Divine Dragon Apocalypse
1 Gorz The Emissary of Darkness
1 Prime Material Dragon

Spells: 10
2 Pot of Duality
2 Gold Sarcophagus
2 Mystical Space Typhoon
1 Future Fusion
1 Monster Reborn
1 Dark Hole
1 Book of Moon
1 Heavy Storm

Traps: 10
2 Solemn Warning
1 Dimensional Prison
1 Fiendish Chain
1 Torrential Tribute
1 Solemn Judgment
2 Bottomless Trap Hole
1 Call Of The Haunted
1 Mirror Force

Extra Deck: 15
1 Chimeratech Fortress Dragon
1 Black Rose Dragon
1 Brionac, Dragon of the Ice Barrier
1 Ally of Justice Catastor
1 Five-Headed Dragon
1 Exploder Dragonwing
1 Stardust Dragon
1 Scrap Dragon
1 Lavalval Chain
1 Wind-Up Zenmaines
1 Ancient Fairy Dragon
1 Red Dragon Archfiend
1 Trishula, Dragon of the Ice Barrier
1 T.G. Hyper Librerian
1 Dark End Dragon

Im in doubt between 1 more of dimensional prison or 1 more of fiendish chains, dragons really lack defense and once red eyes is negated or banished half of my combo is dead. Sorry if my english isnt that good, im not thaat fluent with it.

good job bro. this is an amazing dragon deck but for your answer i think fiendish chain would be better but that is my opinion. anyways i'll rate this 10/10 cuz i didn't know the eff of divine dragon apocalypse. that is an awesome card.
