Comments:
Both your Dragunity and Blackwing decks have a decent structure to them. It seems however like you've stuck to only using 1 of almost every card in your Blackwing deck, except for an odd tech of 3 Tyrant's Temper. I think you'd find you have less consistency issues if you just used more copies of Bora, Shura and Blizzard and took out things like Backblast for another Mirror Force.
Your Dragunity deck was focused around getting Arma Layvaten out and was decent at doing so, but had some odd choices in it too like Summoner of Illusions when you had no fusion monsters, and Dragunity Militum who if you'd ever summoned her would have brought you a used Aklys at most. Your extra deck also contains weak choices like 2 Dragunity Knight Trident.

Game 1:
Late in the game you used Shura and Gale to make a Black Rose Dragon without using the effect, just to attack my blank field with it. It's better to conserve presence then to go for an extra 600 attack.

Game 2:
This game was unfortunate in that you didn't draw any Blackwings and had a hand full of Icarus Attacks. Adding some more basic Blackwing monsters should help with consistent monsters.

Single:
You started the game by givng yourself a minus in presence with Aklys and Brandistock in order to play Mystletainn from your hand. I also think you were planning to sacrifice Mystletainn to play the Arma Leyvatin in your hand. If you'd waiting just one more turn, the Dragon Ravine you drew would have allowed you to gain some advantage instead.
During the middle of the game, you suicided an Arma Leyvatin equipped with Aklys into my Scrap Dragon, thinking that Aklys would destroy my monster. (If sent at the same time, it won't still count as equipped to the monster)
You also never attempted to discard to send Dux to the grave, which would have increased your options all game.

Keep at it and try again when you're ready. You will be assigned to the Slifer Red dorm.
