Deck -
Tester: Blackwings , Testee: Fire Kings
Attitude -10/10
He was very nice.
Deck Build - 20/25
Although it's fire kings, which aren't very original, your build gets style points for competitiveness and creativity, especially with your field spell and main decking skill drain.
14 for competitveness 4 for creativity, 2 for originality.
Skill - 16/25
Your siding was what killed you halfway in game 2 by the end of game 3. Too much skill drain and imperial iron wall being in there was too much for your backrow, allowing me to go in for game. You had control game 1, but not much after games 2 and 3. I'd suggest implementing more stuff that is counter-intuitive to other decks rather than a lot for saving your deck.
6 for control of duel, 7 for siding and side deck, 3 for general skill or nice moves
Ruling knowledge - 8/10
They knew their stuff, but ran into the Kagutsuchi error. Other than that, it was fine. Also the Vulcan ruling.
Misplays and Corrections - 7/10: Forgetting I had Sirocco on board, forgetting about the Onslaught clause of me having a card on the field, and that was about it. You corrected Onslaught, but you also didn't know Vulcan's eff and the ruling behind it.
Result of Duel - 10/20: (0/20 for winning no duels, 10/20 for losing 2-1, 15/20 for winning 2-1 and 20/20 for winning 2-0)
Total: 71/100
Don't be too harsh or too easy on them on each of the above methods of testing.
Congrats on getting Ra Yellow.
