Well, you'll likely need more than the eight slots of threats that's in my above build, b/c that number is pared down due to the presence of extra turn effects and tutors make anything more than that aNobody at my table plays the titans, which is why I want to. Speaking of fatties...
Jin-Gitaxias, Core Augur (Not for drawing, but for locking out the table.)
Sheoldred, Whispering One (Also recursion.)
Vorinclex, Voice of Hunger (Also ramp.)
Avenger of Zendikar
Kederekt Leviathan
Lord of Extinction
[cards]Wurmcoil Engine[/cards]
[cards]Kokusho, the Evening Star[/cards]
Keiga, the Tide Star
Artisan of Kozilek (More recursion.)
Ulamog
Kozilek
Non-fat creatures...
[card:
3q5t4p04]Duplicant[/card] (Recurable exiling.)
Solemn Simulacrum
Phyrexian Metamorph
Nirkana Revenant/Crypt Ghast (Black ramp.)
Sepulchral Primordial
Deadeye Navigator
Kira, Great Glass-Spinner ??
Teferi, Mage of Zhalfir ??
Glen Elendra Archmage ??
I feel like I need more threats, maybe? I've focused a lot on ramping and defense. In Chainer I ran Exansuinate. I think I love that card. I've won out of nowhere with it a few times. Genesis Wave? I don't know that I run few enough non-permanents.
bit redundant. Probably between 12-17 slots is about right, if you're not running Time Stretch.
Aside from the cards you mentioned, you might try:
Bribery, Green Sun's Zenith, Knowledge Exploitation, Tooth and Nail, Diluvian Primordial, Chancellor of the Spires, Rampaging Baloths, Sphinx Ambassador, Army of the Damned, Pathrazer of Ulamog, Consuming Aberration. Maybe Trench Gorger or Liege of the Tangle.
Myojin of Night's Whisper, Myojin of Seeing Winds, and Worst Fears, if we're talking utility instead of threats.
