My first attempt at an EDH deck.

Core concepts:

Lots of Card Draw to help cycle through the deck.

A fair amount of card stealing or copying with creatures. This is the main stall mechanic, by stealing my opponent's creatures and permanents, I can slow them down long enough for me to get a lock on them, while increasing my defenses. If that fails, Propaganda will help, particularly against swarm-style decks.

Teferi+ Omen Machine/Knowledge Pool: This provides the simplest lockout combo. At 6 mana in two turns to lock out my opponents, with Fabricate(and Mystical Tutor to fetch), Treasure Mage (and Vedalken Aethermage to fetch) or just a flat-out Long-Term Plans, the idea is that once this is out quickly, a win condition can be reached after. Long-Term Plans can alos be used to complete any combo as needed when paired with card draw.

Mindslaver+Academy Ruins: Given enough mana to power this, it's an infinite turn lock on my opponent. Paired with the card draw present in the deck, it's even likely that my deck can continue to progress towards a win condition with this lock.

Enter the Infinite+Omniscience: My favorite, if expensive combo, allowing me to play my entire deck. Laboratory Maniac becomes a win condition, though this is more a failsafe to make sure that I don't get decked out while I use my deck to win. Paired with Teferi, i can even flash him in response to a mill.

Spin into Myth: To handle their commander, usually, or a big nasty in a pinch. Though if I have 5 mana, I probably can just steal it.

Glaring Spotlight Thinking of using this to handle hexproof beaters, or to let my beaters slip through. Not sure if I should include it, however.

Feedback I'm looking for: Any obvious cards that I'm missing, anything that looks out of place, overall feel of this deck.
