SECRET FIGHT CLUB (SFC)
Gain access to Secret Fight Club by leveling up past rank 15 in Arena.
Secret Fight Club points are displayed on the SFC Leaderboard - gain points from winning battles, lose points from defeats.
Losing three matches in a row while at 0 points will cause you to drop out of Secret Fight Club and down to 50% of level 15.
Slow ability on your opponent allows them to play a card first but opponent does not attack until the next turn.
Instead of earning Arena experience, players earn Epic Stones.
