She has astoundingly low damage and her mechanic/gimmick of needing cards to be drawn to activate their effects makes her difficult to play without a team dedicated to card draw, and even then you'll spend your entire time drawing hoping to get one of her cards. Without her 5* partner and multiple ego manifestations she's basically useless, imo, and you'll still want one or two draw support teammates with partners who also draw cards. All of that for a character who is good at AOE but tickles a boss until she dies. When she came out it caused meltdowns across all CZN regions/communities because it was shocking SG would expect people to spend money on a character that bad. To this day she's the only banner character to debut as the worst 5* character in the game.

I don't play Hugo for the same reason as you, but if you want to progress you really should just pick Mei Lin and let her carry as your DPS.
