Cards that push contemplative board states: ‘looking for hard to see lines’

Hi, I’m new to cube building, but I have been playing for quite a while and I am interested in building a cube that pushes hard to find lines. So kind of like the puzzles where you try and find a win with the given board state. Certain cards that lend themselves to this kind of gameplay I think are things like intuition or gifts ungiven or shifting woodland. And while a relatively simple line would be Frank Karsten only finding two cards off of his gifts, I also envision trickier examples like a pod deck.

So a few questions:
What makes a card lend itself to this kind of gameplay?
What cards in your opinion lend themselves to this kind of gameplay?
Are there any cubes that you feel fit this description?

Thanks :)
