Same as the Heroes series

It uses troop types, box designs, and character stats that are almost identical to the Heroes series released on mobile a few years ago. It's likely the same company brought over the database and only changed the story and some of the designs. Still fun though. For reference, ads are not mandatory, and there are no intrusive ads during gameplay. However, free-to-play players need to consistently watch ads in the shop to gather resources and troops to progress. Also, save your gems for breaking through maps. Each map has a pink gate that requires gems to pass. Note that you don't necessarily have to go through it, and it doesn't affect the story. Think of it as a bonus stage, but since the rewards are more valuable than the gems, it's advisable to use them whenever possible. That's all!
