You have right, but at the beginning from Bronze to Silver 1 I have met Lord Ariantus only 2 times in the history. That's why I have mentioned in my first articles about Steemit to play 2 elements. I prefer Water and Earth or Water and Fire. You can see what type of monsters your player use in the last games and if you see Lord Ariantus you can easily change your squad. But this is for advanced players :-)
