Quote from WWWolfe »I kind like Glasspool Mimic for this deck. Lots of flexibility on what you could copy (Craterhoof Behemoth, Bloom Tender, Glen Elendra Archmage, etc.) which would almost always be a plus. Or in a pinch it's a land.

Quote from Feyd_Ruin »You may freely transfer anything you have created.
Quote from ISBPathfinder »Generally speaking cards that don't show up have an issue on the card in the database and its not flagged as legal in the format you chose. I am working on Confluence right now and hopefully that will fix it moving forward.
EDIT: I am able to find Mana Confluence now after having fixed the card. I don't see anything wrong with Voltaic Key offhand but it might depend on what format you had selected when searching for it. If you have issues still please let me know.
