@AB-GT-Albin Coliseum ends at 21 January Monday 15:00 GMT+2.
Likely deck issue.
Just make sure your deck is the following:
-No SemiEvos. (Clarice Lv 3 cannot be used.)
-Must contain only cards from the ones as approved. (You can check that by selecting Coliseum in My Collection and it will filter to only the approved cards.).
Note: None of the approved cards are 5 Stars. If a card is 5 stars, its not in the list for sure.
-Must use 2 Clans
-Balanced deck: 4 from one Clan, 4 from the other.
