Match 1
Blackwing vs Mermail 2:0 - 0/10 points
Performance: 18/20 points
Duel 1: no missplays
Duel 2: you got shut down by Dimensional Fissure and didn't draw into it. You should have seen it coming together with Soul Drain and others, so maxing Mystical Space Typhoon (I do hope you run one in side) would've been a very good idea. However, you made no missplay.
Duel 3:
Deck: 18/20 points
Main and extra decks look very good, I've got nothing to add other than swapping Master of Blades for Catastor. I'd personally also take out Scrap Dragon and add Crazy Box for EEV plays (side it, it works well combined with Big Eye).
2 Royal Decree side is decent, however I think Trap Stun is way better this format (I won't deduct points for this ofcourse since it still works) as it doesn't kill your own traps. Shadow-Imprisoning Mirror is also a very good side this format as it hits quite a few top tier decks; Blackwing, Inzektor and Dark Worlds.
Match 2
Madolche vs Blackwing 1:2 - 8/10 points
Performance: 17/20 points
Duel 1: I missclicked Tragoedia here, so that made you OTK.
Duel 2: adding Deck Devastation Virus was a good choice considering you only saw a T.G. monster in game 1. You should have used it when I still had Mewfeuille (its effect only activates if it is sent from the field to the graveyard: "When this card you control is destroyed") in hand. Since you knew Messengelato was in my hand you essentially gave me an extra search and lost the ability to use DDV.
Duel 3: you had good control over the duel and had good judgment using your traps. I did expect Soul Drain and Dimensional Fissure this time, but I guess you don't side them. They're too good to not have though.
Deck: 17/20 points
Foolish Burial is too good not to run when you have Vayu, Zephyros, 3 Blizzard and a Dark Armed Dragon in the deck. I'd take out Cards for Black Feather since it's only useful in turn 1 or when your field is already fully protected; I wouldn't bet on it.
As for the extra deck, find space to add Gram the Shining Star.
Add Dimensional Fissure and Soul Drain to your side.

You've made it to Ra Yellow. Your decks are well built, but you need better cards in your side deck to counter the counters.
