This is a mid-range value deck ... ahh psych. This deck has one goal in mind and that is to -7 and draw half your deck and do this as quickly as possible. The plan is to ultimate on Turn 4 consistently.
There are essentially three mains ways this can happen, but they all involve casting Tamiyo on Turn 1.
There is a 6% chance that you can transform her on Turn 1, involving an additional mana source (6 of them in deck) and either Brainstorm or Careful Study.
But transforming on Turn 2 is the main plan. There are 8 cards that allow you to draw two or more cards on Turn 2. With your natural draw step this works to transform Tamiyo.
There are also 10 draw a card (cantrips) and so you can string two of these together to trigger the transform.
On top of this because Tamiyo creates a Clue, if you have access to three mana on Turn 2 then you can crack the Clue immediately to draw and combine that with another draw card.
So with all these methods there is a 80% chance that you can transform Tamiyo on Turn 2.

This is mainly for me so I can recalculate if card quantities change.
Turn 1 - Additional mana source (6) + Brainstorm/Careful Study (2) = 5.74%
Turn 2 - Draw two (8+2 tutors) = 63.280%
Turn 2 - Additional mana source (10) + Draw one (10) + Clue = 38.45%
Turn 2 - Draw one (10) + Draw one (10) = 7.829%
0.9426 x 0.3672 x 0.6155 x 0.92171 = 0.1963597473206136 = 0.8036402526793864 or 80%

If you can get another loyalty counter on her then it will cut down a whole turn.
There are 11 proliferate (or basically the same) cards that can do this, with also 4 tutor cards to search for one, plus Savor the Moment which allows you to activate Tamiyo again.
There is a 70% chance you will transform Tamiyo on Turn 2 AND give her an additional loyalty to be able to -7 by Turn 4!

Her +2 is a powerful defense tool in the early game. Most creatures are going to only have 1 power during the first couple of turns, so she nullifies those.
To defend against 2 power creatures you really want a toughness 2 or more to be able to defend without dying. So I've really prioritized creatures that have 2 or more toughness that also benefit the deck in some other way. You really want to be casting a defensive creature on Turn 3 to block creatures.
This is the sequence you are looking for:
Turn 1 - Cast Tamiyo, Inquisitive Student
Turn 2 - Transform Tamiyo and +2 = 4
Turn 3 - Cast a creature that can defend. Tamiyo +2 = 6
Turn 4 - Cast proliferate 7 and Tamiyo -7
The chances of doing this sequence consistently is 64%, which is great because what that means is that you get to do the perfect sequence of plays over half of your games. The other games will just mean that you are probably a turn slower.

Turn 3 - Cast creature (19) 91.688%
P(70%∩92%) = 0.64248172999196 = 64%

The way to win is Thassa's Oracle with Tolarian Winds or Sea Gate Restoration.
Aggressive boards - Plan B
Let's say you are going last and each of your opponents plays a 2/2 on Turn. In a 4 player game a transformed Tamiyo is going to get attacked for 3 damage, so you'll be down a loyalty.
In these type of cases casting a creature on Turn 2 is more beneficial as it can block. Turn 2 - Creatures (15) 78.733%
Tamiyo does provide card advantage as a creature by generating a Clue each turn, and in fact just naturally you can transform Tamiyo on Turn 3 if you have four mana to crack two Clues.
