Can Some Body Give Me Some Suggestion On My New Blackwing Deck?

its a really good deck all that missing is one elphin the raven and a black winged dragon and dark hole is legal now so take out onenof the mystical space typhoon and add in a dark hole and a rainbow dark dragon might be good in it..but i suggest to take out the dark armed dragon cause it is allitle to hard to get out and if you have more then 3 dark types then it is useless.
