A Black base Gigaseadramon deck looking to blast through the opponent's security all at once. Utilizing the new Hisaryumon's Sec+1 and DP bonus when played out mid-attack, and Shuu Yulin's Alliance, GigaSeadramon can get a hefty 4-5 Security swing in all at once (depending on if DoruGreymon is also in the stack.) If another Hisaryumon is present in the stack, this large attack also ignores any Security bombs present. These seas may not be Blue, but this'll definitely leave your opponent Black and Blue.
