I love this fat-titted horse, just got my first B+ with her and she was entirely undefeated for all 13 races.
What's a good strat for getting to an A ranking? My cards are pretty mediocre but I really can't do much about that until the universal upgrade mats come out, if they do at all. I've been trying to farm more sparks but I don't know the best way to do that, other than that I have to get one stat to I think 1100.
