You can grind, the bigger autists grind like crazy but even the biggest whale or the biggest autist will lose to chance if the stars align to fuck you.
To be able to properly grind you would need specific support cards maybe horses even from the gacha thougherbeit. I'm not an expert so I don't know if it's still a good time to jump in, or how to reroll now that the must have banner is gone.
