GB are very weak against Amazoness. Against FH/MH it depends on both hands+backrow. So he must be lucky to get only 1 or even no Amazoness during KoG streak. Or a lot of tries.
Whatever he did man ... He managed to reach KOG with a non meta deck in the current meta and this is so GREAT ... I am personally surpried by this .... I love Gladiator Beasts very much and hope for more support to come for them Especially GB Gyzarus and Noxious :D
His Amazoness matchup was handled with triple Cosmic Cyclone. The deck is well built and you can see he knew what he was doing...the deck is teched to the max for most matchups, Canadia being the only power card absent.
