What will be the system for picking civs?

You can pick any civ from the below list but make sure dont repeat same civ in the same round

# You must only pick from the below Civilizations:
#
# Bengalis
# Berbers
# Bohemians
# Bulgarians
# Burgundians
# Burmese
# Cumans
# Dravidians
# Ethiopians
# Gurjaras
# Hindustanis
# Khmer
# Lithuanians
# Malay
# Malians
# Poles
# Portuguese
# Sicilians
# Tatars
# Vietnamese

Okay so one team cannot have two Bengali players in the same game right, but can both teams have one Bengali player in the same game? If not, who can pick first?
And in the next game which is part of the same BO3 can Bengali be picked again?

Btw seems our roster in the first post was changed back to old version, can you fix?
This is our roster:

It is simple, your team cannot repeat the same civilization in the same round, there is no problem if the rival team chooses the same civilization that you have chosen.
