Here's one of my favorite deck ever, the blackwing! Waiting for the new "Raiders" and phantom knights support (ocg now), I realized this build. Very fast and versatile with many skilled combos. The Main one is this by having a Simoon, another blackwing and Blizzard the far north/ or black whirlwind in order to take one more blackwing when you normal.
1. Attivate Simoon's effect. Place whirlwind and add Auster. Normal summon Auster and call back the banished monster by Simoon's effect and add Harmattan for whirlwind's effect (if you preaviously had a whirlwind in the hand, take Blizzard too).
2. Special summon Harmattan without activating its effect on the field and Synchro summon Nothung in the Extra zone. Normal summon Blizzard for Nothung's effect, special summon Harmattan from the GY and add Oroshi the squall from your deck because of black whirlwind. Now attivate Harmattan's effect targeting Blizzard to make it become lv4, special summon oroshi from your hand.
Now you should have:
Simoon, Nothung in the extra zone, Blizzard the far north, the blackwing special summoned by Auster and Oroshi for the monsters and At least 1 Black Whirlwind in the spell/trap card zone.
3. Now, use Nothung and Oroshi to summon Blackwing Tamer Hawk Joe on the field (Absolutely not in the extra monster zone), the use its effect to call Nothung back and then, use Nothung and the blackwing preaviously special summoned by Auster to link summon Raidraptor-Wise strix. Use wise strix's effect to special summon Zephyros from the deck. Then, xyz summon Raidraptor- Force strix by using Zephyros and the lv4 Harmattan as material.
4. Use force strix's effect to add Raiders' Wing to your hand. Special summon it by detaching Zephyros from Force strix and then, call back Zephiros by returning black whirlwind to your hand (avoiding so the Simoon effect in the end phase). Then, use Zephyros and Raider's wing to special summon another force strix and its effect by detaching Raiders wing to add another lv 4 winged beast monster from you deck (generally Bora or Kris). Then, wise strix's second effect activates and set from you deck to your field the Rank up magic- phantom knight's force.
At this point you should have on the field:
Simoon, Blizzard, Wise strix (in the EMZ), 2 Force strix (one of them without xyz materials) and the set Rank up magic quick spell (you won't activate it this turn).
5. Use Wise Strix and the force strix without materials to link summon Verte Anaconda in the Extra monster zone. Then, use Blizzard and Simoon to synchro summon Borrel Savage Dragon targeting wise strix in the GY to equip him.
6. Finally, use Verte anaconda's effect to send the Red Eyes Fusion spell from you deck to the GY (as Wells as Dark magician and Red eyes Black dragon) ti special summon Dragun of Red Eyes.
7. In the opponent's draw phase, use the set rank up magic on your force strix, remote 6 dark monster from the GY and overlap xyz summon Raidraptor- Ultimate Falcon.
And this was the dark combos starting by Simoon. Eventuali, you can also start different the and set up the rank up soul shave force instead of the quick one to use it on you turn to special summon Cyber dragon infinity. Then, after you summon red eyes dragun, use the first effect of Cyber Dragon infinity to absorb the verte anaconda (considering that you should have At this point, 1800 Lp because of both the effect of soul shave force plus verte anaconda which can't be' used first the rank up It you want summon Infinity too).
I just considered the Basic combo. In reality, you could have much more than this.
Enjoy!
