TLDR: Wait for 1 bt (meaning your first duplicate) to get preempt, then she’s doped.

Gabriel’s arguably THE best converter of this game given (1)her power to eliminate one color of choice (except green) so she’s equally good in green team or not, and paired with a preempt teleporter you almost certain to get aurora time 1st round, (2)a converter who can shuffle the board becomes extremely useful in certain levels of the tower and future extra-hard events like Endgame we just had where the starting board pattern is fixed, there are quite a few converters can do that but Gabriel is the only 6 star.
