i thought passives (clones, barriers, buffs) are determined by overall Team Init? the higher ones will always go last. In other words, the passive barrier will cancel out the one with the lower team init (assuming both teams have ninjas with passive barriers)
for the individual mystery prompts and std atk, i think that's determined by individual ninja init.
init is important, but if the power difference is not a lot, sometimes i can win with control team (chaos, immobile) it's usually 50-50. how, what and when u do the mystery prompts is important too.
