Scrapped.
An infinite exile mill combo with
Grimoire Thief
that comes out on turn 4~!
There needs to be another name for "exile mill" ... lets call it Xill!
That is best conditions for the Freed from the Real
+
Grimoire Thief
+
Paradise Mantle
combo. And as we all know, best conditions usually never happens, but are very attractive. And when they do happen, "wow".
Freed from the Real doubles as a creature control, I can put it on my opponents creatures to tap them before they ever get a chance to attack.
Attacking with
Grimoire Thief
(if you ever get the chance) or tapping him for mana because you equipped Paradise Mantle on him allows you to Xill the opponent, which is very useful in its own regard so feel free to abuse it whenever you can.
Muddle the Mixture, Drift of Phantasms and Tolaria West are here solely for the tutoring, but they have added bonuses of being difficult to prevent, and being useful when I don't need them as tutors.
Remand effectively acts as a timewalk and can also be used to effectively analyze their hand, and prepare for the next game. You then know one card and can prepare for that card, in certain decks that might be the one card they need to win so keeping a check on it is useful.
Serum Visions, three card filter, one mana, I only have three cards to my combo with a tonne of tutors, bonus~
Cryptic Command is my all-round control and cantrip and is effective against numerous types of decks.
Surprise! Snapcaster Mage, I now have an answer to that.
Unsummon and Echoing Truth can be use in two scenarios, either permanent control, or anti-removal of my combo.
Isochron Scepter is useful in so many situations as it can take whatever you have in your hand and use it indefinitely, or until they throw artifact hate on you. With Remand you can have an indefinite Time Walk, or with Echoing Truth have control over the entire non-land board. Versatility at its best.

Sideboard explanations: Do need a bit more help with the sideboard, mono-blue still is not my forte.
Chalice of the Void to use against decks that rely on one CMC for a majority of their deck. Like goblins. Put down the chalice for 2, and every one drop goblin is now countered. Have fun~
Hurkyl's Recall to be used on artifact decks, can be used in conjunction with Chalice of the Void to make your opponent's very angry.
Pithing Needle against combo decks or control decks. Using this on a planeswalker or a Deathrite Shaman and the like.
Tormod's Crypt is here to us against the graveyard interaction based decks.
And finally, Witchbane Orb against discard, mill and burn decks.
