Don't really think there is anything worth getting in this set of events other than katen and tsi Ichigo. It was shit time to top-up 20k gold unless you took advantage of the glitch that happened. If it was me I would save the gold for another time and buy a few good assaulters, or if you really want to buy someone now then go with tsi Ichigo. I would buy B.Renji and Kensei for your team, and work on getting them t1 along with your Kirinji.
