I know that using the curse reverse would have been a really bad play, but I still somehow wanted to see the Sushi challenge blocked after they protected it. But I think this protection wasn't that good timing wise as they could have used the tracker to see whether Adam and Tom gave up on the house of cards and reoriented themselves before pulling the trigger.
Ignoring the unlock was definitely a bad play, but I get how they missed this. And too bad that you can't pre-complete challenges. The timing of the bamboo challenge drop would have been insane otherwise.
While the rice challenge is now removed, we will still get to see some new challenges "tomorrow" and Adam/Tom still have a reshuffle to not get too stuck again. Especially considering the Shinkansen move that Ben&Sam are planning. I hope they will stay neck in neck for a while so that no team is in a huge lead and the other looses prematurely or so
All in all I hope the season will keep them neck in neck till the end and will not prematurely have a winner decided.
