So wtf do I do? I have bourban and rice shower up to a C on a failed career. Do I use them as trainers on my lesser star horses to train them up as well and just keep “leap frogging” better trainers per goal attempt?

Since I have bourban do I just save my carts until next banner? Should I buy more support cards? Here’s my deck.

Never really played a gacha before and thought this one looked funny. I’m enjoying the grind, if I’m even doing it right that is.
