They were open for 24 hours and it was basically the one who had no life would win
You had to fight 24/7 to stay up top and would only fight Arena meta teams with non meta teams. It started out as a whale tournament with crystals and then ally points and even then it was a game of "either i use my ally points in this tournament or save it for the next"
A lot of backlash got it removed. There was some exploits with setting defenses, and it just punished anyone who had a shred of life
You also needed ally points to refresh your units so you could use them again for battle also people found a way to game the system where they would constantly beat each other and get one and two

I do miss the 6 hour flash events though.
