What exactly means "Most used Troop"?

[Barney_Stinson]

A guildmember ask me today how this troop are be chosen.
I say by the number of spell casted.
But his troop is sparklesack… He played the thief team a lot but rarely use him, hundred times more eggthief. Sooo, i don’t know.

What counts it?

Number of spell casts (x per battle)
Number of troops per battle (1 - 4 per battle)
Number of being part from the team (only 1 per battle)

My is for ages Krystenax, i used him (in the good old 3-match times) normally 2-3x in my mainteam, so thats possible for me. Gowdb says so 42k… Mmh 42k Kry casts? Really?

Mmh…

It’s just the amount of times that troop shows up in an invade team. Databases have Krystenax very high on mine because I ran two at once (that counts it twice).

It does not count other modes. Or mine would look very different.
