Frankly man, I didn't believe it at first but now I see that in fact there are two spikeshield KOG decks (and I was like O_O!) but that's not all; there are also Flying Fish, Hazy Flames, Psychics and Armored Bee KoG players as well this month! Dude, that's just awesome! People really believe in their cards, they are like:
"I can't afford to lose! ORE NO TAAN!!!, DORO! =))
Haha so, how do you say furries are broken? No way! The problem is not this deck, but the player!
You're funny. You can become KOG with any deck with patience and skill. But it looks like it's easier to get it with fur hire :) Mostly because you don't need any skill to play it.
And a deck with no skill, is usually a broken deck.
