A message from repulsive end, founding father of lineupology:

"BROADCAST FROM REPULSIVE_END6319: A NEW DISEASE IN LINEUPOLOGY HAS BEEN DISCOVERED: IT IS CAUSED BY A LACK OF DEPTH IN A LINEUP. IT HAS 4 STAGES, IT IS TEMPORARILY GOING TO BE NAMED “PUTIN” UNTIL A FORMAL NAME IS PLACED."

Ill explain what putin implies. A lineup has putin when it is very top focussed. It is good to have some mid tier creatures in your lineup that can do tournament battles while still gaining a lot of trophies. Using high tier creatures gives lower amounts of trophies, so having putin can result in harder tournaments. To fix putin, you have to get creatures that arent right at the top of your lineup, amd should instead be somewhere between 10th and 20th in the lineup. Now having low stages of putin are not very impactful, however at high stages tournaments could become harder and much less time efficient.
