Will season tokens expire?

I’m assuming they will, but when the season ends do all extra season tokens go away? Or is it possible to stockpile them for season 2?

The Time Warp tokens will not be useable in the upcoming next season.

From what I understand, as soon as the season is over, any leftover tokens you have will be gone. So basically, use it or lose it lol. Season two will have completely different tokens, and (hopefully) different rewards and units. (And hopefully no alliance coins!!)
