damn typo, thanks for the heads up.
the idea of haunt is that the enemy's permanents are being haunted (as apposed to a home or abandoned hospital/lighthouse etc) and unable to function in the status quo for 1 turn.
my thought process started with "hey, haunt would be a cool card name, what would it do? well, it affects permanents, but what would 'haunting' do? it would probably scare everyone into paying attention to the ghosts and try to not die until the haunting goes away, so i guess it will be like a stun of sorts."
then figured maybe make it targeted on one permanent, but how is that on par with earthquake or destroy/steal which are already cheap cards. so haunting all of the opponent structures seemed to fit, for one turn, which lends itself nicely to be the sundial for permanents, and i thought that was an interesting concept.
as for the soft permanent control idea, its an interesting thought. maybe "Linger" could do something to a target permanent as a clicky effect. but what exactly it does i am not sure about yet, ill have to think about a balanced idea to do to a target permanent for a low cost once per haunt. my first thought was to produce a skelly every turn that the permanent was used, but on a pillar or weapon that would be every turn.
