I reached KOG from legendary 1 to KOG. The key is Amphibious Bugroth MK-3 with the skill Mythic Depths. You can avoid Mirror Wall and Super Rush Headlong with MK-3 and trigger all the Enemy Controller and Windstorm of Etaqua from your opponent.
MK-3 is the game breaker against many popular decks today, e.g. Tea deck-out. It also increases the winning rate against Pheonix.
I used my Phoenix deck to climb from Gold2 to Legend3. Been bouncing up and down between Legend3 and 2, then I decided to switch over to Mill. Got to KoG straight after that with 10 winstreaks from Legend2.

Just got kog with this mako - hammer shark deck. I hope this will help you guys analize the currrent meta.
Magic Drain came in clutch when opponent tried to econ take my monster and v SRH, and many other annoying spells.
A pretty standard list of statue control, I will most likely will take out Dream clown and Arm shield for a 3rd Heavy Knight and Curse of Anubis, when I get them.
This deck have a decent matchup against some popular decks such as Phoenix, REBD, Mills, Weevil Burn and sometimes Toons or Naturias. Try to stall as you can and make huge damage with Lava Golem or sending burn effects, Warm Worm for winning the shadow game race, and supporting cards like Magical Arm Shield or the Blast for Tribute for biggest situations.
Deck is built around monster removal and clearing back row. Often requires an offensive yomi ship and sacrificing life points to win duel.
The deck is simple revolves around the Black Dragon's own cards and of course the combos we can take with them a trap. Ultimate Providence to be Counter of Fenix, I went from legendary 1 to KOG in at least 20 matches.
