Hi (not fraggle but i can still help you
To enter the
ELo ranking you need to be level 20 and to have a
Elo compliant deck (no doubles and the sum of the levels of the characters must no be over 25, you can have 8 or more cards in your deck, but obvisously, 8 is the better way to start)
When you are
Elo compliant, a pillz will appear next to your name in the game lobby. You still can be challenged by everyone, but you need to play against other
Elo player for the fight to be registered for
ELo rankings
When you begin in
ELO, you will start with a value of 1000. Then, after each
ELO battle, your value will go up or down based on the result of the battle and the
ELO value of your opponent.
You should find helpfull information reading the
Elo part of the game help.
Enjoy
