It seems odd for there to only be 16 cards in that set, but I guess that's just product production. Anyway on to the deck...
1) Adding creatures that let you draw outside your regular phases can be beneficial to your deck's strategy and combos well with the artifact. IF you add reckless scholar and catalog you can draw into a lot of cards quickly and has a minimum downside. So that's draw 2 cards and discard 1 for the scholar and draw 4 cards and discard 1 for the spell.
2) I'm seeing a lot of enchantments in this deck and it can probably work towards your advantage depending on how you run them. If you decided to add WHITE to the deck (and maybe remove the Kiora and the Nissa Enchantment) then you can add cards such as bygone bishop, expose evil, survive the night, and even thraben inspector. The Clue production will be faster and you'll have a steady board state.
3) Your land choices are not that bad. Just keep in mind the color ratios that you need so your deck doesn't stall out on you due to lack of a certain color.
Really when it comes down to it, how you decide to run the deck (whether it be aggro, mid-ranged, or control) matters most. There's no point in making a whole bunch of clues just to sit on the board (unless you're playing confront the unknown).
Hey G.Moto. (I never get notifications on your posts, so sorry if I am not replying!) I will scan through and see what I have yet to reply to.
Actually, the welcome set is much larger but incorporates cards from current sets like
Zulaport Cutthroat from Battle for Zendikar.
As for the deck, it's mostly just for standard casual at my friend's house. I like playing experimental decks. It's mostly control based, using
fleeting memories, clue production and milling with
Sphinx's Tutelage utilising the extra draw steps from cards like you have suggested and clue sacrifice.
Thanks for the advice on the deck, I wanted to try a mill deck that utilises green and blue, rather than splash another colour. I mean I was playing with the idea initially because
Bygone Bishop fits well with the mana curve, and produces a lot of clues! but today cements the fact that I don't want to run a three colour deck, because I got destroyed at a draft FNM using one. haha I will add 'catalogue' though I will substitute
ongoing investigation for it! There are a lot of blue SOI cards I was thinking of adding, (
pore over the pages) unfortunately, space is finite. and the people I play with are punishing, it's London so...
