So the only way to use Hecate is to buy her on one round and set up the columns for 2g - then next round you have to both win Ares AND Ares has to be in turn order BEFORE Hecate or someone else will move the columns before you get to use them...?
seems like you could get boned very easily with this one ...??? A waste of an entire turn and 2g quite possibly.
To pull it off is the counter to how powerful the ability is.
Idealy you want to activate her on your two islands or on an opponents island where he has to spend time to move people to to defend. you can delay that by denying them Poseidon.
