it's likely more of a SR/SSR deck issue than a legitimate skill issue, you figure out how to train efficiently gradually. a lot of the insane horses posted around here, like the oguri, are from gigawhale decks, as a f2p you can get 1200/900/600/300/300 but nothing like 1200/1100/1000/450/450 without whaling and having insane legacies.
