Took me all 10 tries to get the guranteed 5*. But it was Warfarin (which I heard is pretty good?). Haven't spent any resources on her yet since I just started and wanted to get my main team ready for the event. Not looking at guides since I want to solve all the maps on my own.
Just cleared GT-5, which is great since I believe that's the main one to farm for the event, so I can auto-there while building my team in prep for GT-6. Quite happy with my progress for a less than 2 week old account.
I'll wait for a few more banners to see what other 5*s I get before using the pick ticket, but leaning towards Projeckt Red or Liskarm
