My 4 are:
1. Chris Underwood
His video on ET Canada impressed me and he lives near me. I really hope he does well as a local here!
2. Wendy Diaz
She seems to be a really fun character and got to be in the original season reveal trailer.
3. Victoria Baamonde
In an article I wrote, I see Victoria as a Christian-type player that isn't nearly as obvious. She has done so much research and definitely has a chance at doing well.
4. Aubry Bracco
Tried to only include 1 returnee and I see Aubry standing a good chance. She did almost win her first season but her edit on Game Changers was so under the radar people could easily underestimate her.
