20* Brawl-for-All is a simple round-robin tournament, cheap (200 clintz) to enter, with very simple scoring rules. The prizes for the top 3 places will be 45, 30 and 15% of the overall jackpot. The only real difference is the format - stricter than ELO, even! The maximum level count of your deck can be no greater than 20, so dust off those 2* and 3* cards, and see what you can do!
This is my first event though, so please feel free to point out any mistakes I'm bound to have made.
