Surrak, the Hunt Caller will take Whisperwood Elemental's spot, but Shaman of the Great Hunt is a card draw source for the deck. Also, the caryatid is to expensive :(. Thank you for your help xtinguish

remove the island you have way too many !!! look at the top chart for the card cost and land mana. Use that for reference to see what you kind of land you need

Well I need to make sure when I sideboard I still have enough blue to use the spells in the sideboard.

island in the sideboard

Nah, it's better to warp the maindeck's land so you can have a versatile sideboard then to warp the sideboard, because you play more games after sideboarding then the original mainboard.
