One more agenda you can use with Titan is Executive Retreat. Doesn't hurt to have an extra Draw 5 Cards ability. Wouldn't be in my suite personally, but if you wanted to have minimal agenda density it could be good.

I was just getting my mind completely blown by a non-unique upgrade Kati Jones until I suddenly realized that it doesn't say "Place 3 credits from the bank on Shell Corporation." Unless that's a typo, my mind is no longer blown. It's more like a sorta different Sealed Vault.
