The Cursed Key seems to truly be cursed. Whenever I get my hands on it my run will always end in disaster no matter how good my team is, lol. The funniest example of this was when on a run with the key, I barely managed to reach Cynthia, and then pulled off an incredible comeback against her when I was about to lose, only to then still lose by decision because her final tiebreaker percentage thingy was 1% higher than mine...
