You don't know anything about Guardian Summoner.

First, the game was shut down only three months after they released it. I know this because I was playing GS waiting for the international release that it is now unlikely. Second, they gameplay was pretty different. It was a card game without any city building gimmick. You controlled 3 summoners with a deck of 6 guardians. The guardians had different elements and types and you could chain a guardian with one of a summoner next to you if they had one compatible guardian. By doing this, you filled a gauge that activates the summoner special ability, like healing, dealing damage or fill the gauge of the other two summoners. Also, there was an actual story and the summoners interacts with each other. The only real similarity was the "Archwitches", that were also used for ranking (I could top 10 it because nobody was really playing the game)

Probably you are thinking about The Knights of Mira Molla, but other than building your city, it is more like a Clash of Clans game.
