I just had a 9-0 run today (game crashed when Burn killed the last enemy, got a loss) with this lineup;
Hero - Orpheus’ Dischord
Musketeer
Warlock
Chimera
I think I lost 3 Troops in the 9 matches in total. Every match was like playing my PvP Team, over in less than 2 minutes and massively overrunning the opponent.
Anyone else remember the lineups they have had in Arena where you just dominated and it was actually a joy and not a grind like usual?
