Season 1 Token player

I'll have my 32nd token this week, but Season 1 ends next week.

The reward pack mentioned in the Field Pass -> Sets->  objective mentions you get a choice of 10 Champions released during Season 1. 

If I turn in the 32 tokens, will all 10 players be available, I'd hate to miss the chance at an 87 champion that drops during the final week of Season 1.

I need to add a couple of 87s to my roster because "The Run" level 4 has been giving me a hard time. I'd hate to give up any opportunities to get tokens, assuming they're usable during Season 2 (I didn't see a season branding on the 31 tokens I currently have, so hopefully any leftover tokens will be there, like the Season Tickets.
