Ravnica Recollect is at $49.99, Compulsive Research and Drift of Phantasms is at $24.99, Disrupting Shoal is $3.21.
Interestingly enough, the cards are still sorted by what their prices roughly should be on my wish list when you order it from high price to low price. Almost the same thing with my Trade List, but things are a little wonkier there.
