Maybe it´s a silly idea, but, like SoF, why not give a water card when removed? Like Purify.
Or maybe do it depending of the turns since played SoP. More cards or a more powerful one every turn you wait to click and remove. Can be +1 Pillar/Turn waited, for example. It´s a bet, because PC exist. It would be a buff and I think It would be funny, too.
Thoughts?
