At one point in a Yooyuball game, a group of spectators all held up signs. However, there was an error in making the signs, and they didn't really make much sense...
However, the missing letters (circled, above) did spell out something at least marginally related to the Altador Cup when they were unscrambled.
What word can be spelled from the missing letters? Please enter only the word with no other information.
