Forum:Black Harpies Deck

Heres a current deck im working on for regionals in my local area later on in April, i have combined two totally opposite winged-beasts that many people consider to be enemies into my deck haha but what can i say? i just couldn't resist because they both have their advantages harpies=backfield control and blackwings=swarming and then the beatdown, not to mention the entirety of this deck is to obtain a Dark Simorgh lockdown with the use of either Anti-Spell Fragrance (if i clear thier backfield, they cannot set so no traps :D) or with Royal Decree if they have cards already set before Dark Simorgh hits the field

Black Harpies Deck
My Extra Deck will contain the Following when i finish
 * 2 Blackwing - Armor Master
 * 2 Blackwing - Armed Wing
 * 1 Blackwing - Silverwind the Ascendant
 * 2 Stardust Dragon
 * 1 Red Dragon Archfiend
 * 1 Goyo Guardian
 * 1 Brionac, Dragon of the Ice Barrier

The problem is that i have no idea what to side deck for all of today's mainstream decks D: haha im also up for minor changes to my main deck :D
