This achievement has probably be done by a majority of players during tournaments, but now with the recent changes in tournament rules (recent poll), it seems we are getting less and less (never anymore ?) tournament including common creatures.
So now, the 2 options left we have to achieve this achievement are :
1- To massively drop in arena until our “common team” is able to bring us victories. (And ruining experience of a lot of players during our drop and our climb back.)
2- To massively invest ressources in common creatures… (Which is basically impossible for a player recently arrived in the game)
Don’t you think it is time to modify this achievement ? Maybe by allowing it in friendly battles ? (Right now, friendly don’t work)
Thank you for reading.
