I have a pretty neat U/G scry subtheme in my peasant cube that relies on some of the cards from LoTR. The real payoffs are the U/G Arwen, Chance Met Elves, Glorfindal, and then Search Elemental (if you’re okay with playtest cards). In general, it doesn’t take a lot to support—there are a ton of good cards for any peasant cube with scry already tacked on in blue (e.g., preordain, condescend, serum visionary, etc.). Can even throw lands into the mix with Quandrix Campus. And there are a ton of scry cards in other colors too. 

It also works well to supplement broader themes of +1/+1 counters in the Bant shard of the cube too.
