This is the KOG deck i used from gold 3 to kog.
I reached kog using this Garlandolf red eyes deck.
Simple ice barrier deck using Gale Lizard. Synergises with Moray of Greed. Stalls for a turn whilst removing a monster meaning that I can possibly use my Magic Triangle of the Ice barrier on the back row instead. This means that I can deal with an econ that may have previously caught me out.
I use vampire lord to special summon it with gozukis effect and I have storm in this deck since I can activate my traps and spells before destroying them, it was very helpful with the amount of toons, balance, and mako decks in legend ranks.
I was testing around a little with soul resurrection, windstorm of etaqua and return Form the dark dimension which I kept in the end.
It's quite helpful in reviving a ill bud or zombie dragon after being banished by gozuki. In general my deck seems to be running smoother with it, since it adds a solid option to get a bigger mob out without relying on I'll bud being on the board, or having them in hand with gozuki on the board.
You know the right use of this deck, I think that I don't need to explain myself.
Used this from legend 1 to kog. Took roughly 40 wins in total.
