What game is this??

I can't remember the name. The game involves building a kingdom, making gold, wood, iron mines I think. You then summon these heroes and villains to defend your castle. You make teams of them. You can also attack other people's castles as well. You land on some sort of a bridge and fight their defenders until you get to the castle gate. You beat the gate defenses and if you're successful you get resources.

Unfortunately this is a very generic description for medieval-themed tower defense games, which kinda abound in the Play Store. Do you remember anything more specific? A key term in the title, release date, maybe character design/names perhaps?
