So one card more makes Shauna good?
Is it possible that hindsight bias makes you think that Shauna is bad, because PONT was at one point a thing?
I personally think that Juniper/Sycamore should have a hand size requirement before you can play them. Munchkin has a few cards that do good stuff for a hand discard, but require a minimum hand size of 3 to play.
Then again, I don’t like the idea of “staples”. I think every card should have competition to the point that player preference or synergy dictates what you see played. (Just my opinion.)
