KC Report is a source of Duel Links data. Here is a list of items you may want to refer to using KC Report:
Top 5 popular cards by pack
Top 5 popular skills by rank
Examples of KOG decks
How does it work?
The most interesting point of the feature is that you can see what cards and decks were used most a week ago, and that enables you to see the current meta and helps you to build competitive/anti-meta decks.
KC Report 3 [June 1 - June 12 2017]
KC report 3 contains data collected from [The World Championship 2017] Qualifiers and Final Qualifiers round.
Trap Jammer is a very powerful card and costs almost nothing to obtain. Also Mirage Dragon. You can even change your Xing Zhen Hu is also a very underrated but powerful card. People who complaint about Mirror Wall are just lazy to think about answers or counterplays
With more OP cards, this game lost its meaning. In the old day, if someone used Exe Rider or Battle Ox, i thought "Wao, he/she is lucky". Now, if someone uses those cards, i think "He/she must be newbie".
So what is wrong with that? Cards like Axe Raider were included as UR because Konami did not know what would be too OP for this game. Thankfully the game has been evolving in a way on which we can have more powerful cards without breaking the game. I am pretty sure that the only thing breaking the game are skills which are also being balanced. An excellent job from Konami.
Its literally this entire website, but with more accurate statistics on top decks, and without these random shitty deck recipes. Also there's its not plagued with fake probable news like marik or valkryie card packs
The valkyrie pack is just a rumor but the marik is definitely real. There are already many sources available around.
Don't really get what you mean that it's the entire website since KC report just shows what people commonly use since they go with the meta. Obviously most people will go with the ones that are less of a hassle to make which leads to most of them using dino kingdom deck.
Obviously KC report doesn't show much of Gravekeeper deck's strength, Harpie decks, Relinquished or even the Spirit Ryu tricks. Harpie hunting ground skill is rare drop, gravekeeper requires a lot of investment and etc. To say that the KC report shows all of these things just makes me lol...
