And Black becomes the final eliminated athlete before the finals. Considering how they placed dead last in S1 and they would've been dead last in this season if I wasn't so benevolent, this is a great improvement!
Black's highlights:
Shared gold medal on Day 4
Another gold medal on Day 7
Bronze medal on Day 9
Gold medal on Day 11
Silver medal on Day 14
Another silver medal on Day 16
Bronze medal on Day 17
Another bronze medal on Day 19 (aka this one)
Ignoring the initial slip-up, Black was an excellent player this season.

With that out of the way, we're left with the final 2:
Purple, a really skilled newcomer
Cyan, who rejoined thanks to Green

Who will win it all?

Hey, the finalists remind me of Blue and Brown on my Algicosathlon
