Forum:Potential Blackwing OTK?

Hey everyone, I was in the middle of building a blackwing deck when I noticed that there may be a potential One turn Kill involved. Please let me know if this is indeed possible, or if there is a technicality that I'm missing.

ok, you'll need the following cards:
 * Blackwing - Sirocco the Dawn
 * Blackwing - Bora the Spear
 * Blackwing - Gale the Whirlwind
 * Blackwing - Kalut the Moon Shadow
 * Black Whirlwind
 * Swallow's Nest
 * and maybe Shrink although it's probably not necessary.

The idea here is the following


 * Start off by playing Black Whirlwind
 * continue by special summoning Blackwing - Sirocco the Dawn
 * use black whirlwind to add Blackwing - Bora the Spear, then summon it
 * Use Black Whirlwind again to add Blackwing - Gale the Whirlwind to your hand and then use it's effect to special summon it
 * Activate Blackwing - Sirocco the Dawn's secondary effect to make Bora gain attack points.

This is where I get a little fuzzy and don't know if it will work:


 * Chain Swallow's Nest to Sirocco's effect, targeting Sirocco to special summon another Sirocco
 * Activate Sirocco's effect once more.
 * If Everything works and I'm not miscalculating, Bora should at this point be 8300 atk
 * Discard Blackwing - Kalut the Moon Shadow from your hand to make it 9700 atk
 * Now, if your opponent has a monster with anywhere 1700 atk in attack position, activate Gale's effect to half it, if their monster is in defense and has more than 1700 Def then there's not really much that can be done.

This means that as long as your opponents monsters has less than 1700 DEF if it is in defense mode and anywhere between 1700-3400 ATK, and assuming (a lot of assuming, I know) that your opponent does not have anything like a Sakuretsu Armor or Negate Attack etc., then you can hit your opponent for at the very least 8000 LP Damage.

Now my question is, did I miss something? Did I misunderstand an effect of any of the above cards, or is this possible?
