Here's how this will work. I will post a LETTER and NUMBER in the comments, the last person to comment a word that starts with the letter I post, and has the same number of letters as the number I post will be NOMINATED FOR A HEAD TO HEAD CHALLENGE.
They will choose a player to drag into the arena with them and they will go toe to toe in the same challenge and whoever is slower loses. The final player remaining will choose who is eliminated from this round.
E.G. if I post 6 - L, you could use the word listen
