I was using his powers exclusively throughout all of the game and hardy the only thing he could do is keep his workers close but then he won't be able to use Hydra anyways.
Circe renders Hydra completely unusable - what do you guys think?
Start of Your Turn: If an
opponent’s Workers do not
neighbor each other, you alone
have use of their power until your next turn.
End of Your Turn: If none of your Workers neighbor each other, place a worker you control in one of the lowest available unoccupied spaces next to the Worker you moved. Otherwise, remove one of your Workers from play.
