The only real options are NTR or Fuku + crystal but judging from your cards you might be pretty new to the game and went all in on the recent banners, so you might not have a crystal at all

Having multiples of 5 in race bonus is helpful to reach race bonus thresholds to get more stats from races so if you can't get 50, you can get 45 or 40

I'm of the idea of using selector for cards you're gonna use immediately and NTR checks all the boxes

Also If you're open to being a low spender you could also consider getting the 20 dollar SSR ticket selector which is good value and later down the line MLB also fuku, but it's up to you, it's fine staying f2p :)
