Shelly Moore
Season 13- 6th Place
She played both sides beautifully all the way to final 7 further than anyone I can think of in the BB game. She even played the veterans. Had Pandora's box not existed She along with Kalia (who'll appear later) and Porche would have had a golden road to final 3. Shelly lied when she needed to lie and knew when to back stab who. I truly hope to see her in a future season.
Note: This list is based purely off of gameplay, NOT likeability. Some of the people on this list I disliked in their season, but there's no denying they played a good game.
Hint for #15: Almost came back for a second chance, Post-All Stars
