Pithing Needle only deals with Wasteland, and is not very compatible with the Chalices.
Also, I'm not entirely convinced a creature like Sea Sprite is the best choice. SotF gives your creatures Pro red anyways, and Chalices do quite alot to mitigate the deck's suseptibility to burn. Soratami Cloudskater is something I'm considering, but I'm still trying to determine if I even need a fifth type of creature.
Running one Pithing Needle maindeck didn't seem very helpful to me. When I dropped a Trinket Mage, I would fetch Chalice, as it almost without exception would do more to improve my position then a solitary Pithing Needle would. I think a better approach would be to move all the Needles to the board, and then when playing against Goblins or whatever, side out all the Chalices and side in the Pithing Needles.
