I think
intangible virtue is your weakest choice in the deck, and a prime candidate to be replaced with something else. This is because your early and middle games look pretty weak and it seems doubtful you will have a large enough army, especially if the opponent plays some removal, to take adequate advantage of the board-wide boost offered by I.V.
At first glance, your mana base appears weak. However, after further analysis it is better than it first seems. 20 lands would not be nearly enough but when you consider the Energy Taps, the Etherium Sculptors, and
Tinker's ability to bypass the cost on the searched-for card (presumably Sphinx Soverign) you see how the deck could function.
Although,
Energy Tap won't produce much until you get your first expensive guy on the table and
Etherium Sculptor won't help you play Oona.
Tinker also suffers from a lack of cheap artifacts to sacrifice; there's only
Etherium Sculptor in the early game so you are chipping away at your mana solutions when you sac one.
All in all you have a fun deck that will work sometimes but is too specific in the combinations you have to draw in order to function consistently. I would suggest that you commit to either paying for your spells or cheating them out, not trying to do both. You might consider a larger army of cheaper faeries if you want to get full impact from
Intangible virtue or
Glen Elendra Liege.
Alhammarret's Archive and
Mirror Gallery could be one-ofs since the second copy drawn is a
dead card. Lim-Dul's Vault seems like the best-placed card to fix the deck's problems - you might find room for more of these or other similar cards.
Retraced Image is heavily dependent on having other cards in the right places at the right times, magnifying lucky games but harming less lucky ones.
What sort of direction do you see the deck going in from here?
