I would leave in Kor Skyfisher and replace Steppe Lynx as the lynx has been fairly underwhelming in my C/U cube, there is a lack of fetches and is a horrible topdeck.
I would not put Naturalize in a cube, it is far to narrow. You can look at it this way; naturalize can be considered a sideboard card, whereas you will maindeck Wickerbough Elder every time.
@ buh-roken: This project is intended for "regular" cubes. (Therefore your list has not been added to the permanent database.) The recommendations for your list almost exclusively consist of rares and old cards.
