Nice game idea and great art!
I agree that a random can just screw you over if you don't draw a candle cards (or right candle cards). And a decision making is somewhat simple, since you always want to play candle cart, you always want to play a binding card that binds zones you already bound and you never want to play a binding card to an uncandled zone if you have other choice.
But if you are going to expand this idea, I think this would be a great and really unique card game!
