>>714516731Umas will have terrain that they're better or worse (Turf/Dirt), distances that they're better or worse like short distances (sprint) or long distances, and they're going to have "positions" that they could be better or worse (front runner, pace chaser, late surger, end closer) because there's stamina involved so being 1st isn't always the objective (for most of the race anyways), also every Uma has different "Unique Skills" (kinda like super attacks) and different sub-skills too. So yes there's a lot of differences but Support Cards are still more important.
>i got the big booby horse support card and 2 copies of another ssr so i figure this is the account i'm keepingSuper Creek? That sounds good then, you could try to reroll to get an even better combo but it depends on variety too, you want to have at least one SSR/SR card of every stat (Speed, Stamina, Power, Guts, Wits)
