One of the worst gachas out there... All depends on your pure luck, because no banner is guranteed. From start the game was +- balanced so player was not so dependant on a broken units, but as the game progressed they implemented more and more limited overpowered units, and if you are not lucky to pull them and end on duplicate pulls stream, you are pretty much forced on lending the units from fortuned people, so basicly as some lowlife. I dont recommend this game especially when you are new player. Also all guides spins around same few overpowered units, so basicly you'll have a hard time finding anything fitting to your rooster. There are guides with low rarity operators but those are the hardest guides to do out there, everything must be super perfectly executed, and you must have everything exactly as it is in the guide, all that will give you lots of hard time and repeating the same level.
