The standard early meta teams looked exactly like this, but they run Celesteela instead of Kartana because it gives a safer switch thanks to its bulk, another Ground immunity you really need and you can run a Special set since you already have 4 physical attackers.
Edit: didnt notice you have both A-Marowak and Arcanine LOL as Marcus said you already have an Intimidate user so i would try something else instead of Arcanine such as Porygon2
