As the Turncoat you’re able to play for both teams, but if you want to win then you need to predict what day the game will end and what team you’ll be on during that day.
If you want to lock into one team, then try getting killed whilst you’re on that team. Your ability will no longer work because you’re dead, and you’ll stay on that team.
Try hedging your bets as to which team to primarily play for. If you play your cards right you might be able to swing the game in your desired direction at the last moment.

Choose which team the Turncoat starts the game on. Every night, wake up the Turncoat and tell them they have changed team. Send them back to sleep.
