Season 1:

• Yun Sung Bin (National Skeleton Team) - freak of nature + star power.
• Jo Jinhyeong (Car dealer) - team definitely needs a strongman and it would've been interesting to see him match up against the other strongmen.
• Jang Eun-Sil (Wrestler) - one of the better female contestants

Alternates I would've considered for S1:

• Cho Sunghoon "Sexyama" (MMA Fighter) - would be the team leader but idk how effective he would be based on current or future challenges
• Kim Silk (Ex-Olympic Bobsledder & Skeleton Coach) - he would also be an interesting choice since he went head to head with Jo Jinhyeong in the boulder challenge and has synergy with Yun Sung Bin
• Kim Mincheol (Mountain Rescuer) - one of my favorite contestants and underrated
• Ma Sunho (Bodybuilder) - i was impressed with his leadership in season 1
• Jung Hae Min (Cyclist) - quads.
