For the longest time we only ran the other 4 titans, but once we added Frost Titan, we realized that it is still quite good, even if it's not as good as the other titans.
I had a really sweet Birthing Pod deck on Rotisserie draft, was able to slow roll actually picking up it really late, since I was the only one interested in it. Heavy build around and doesn't come together as often, but for those times that it works, it is still worth the slot for me.
PS. I missed the discussion on Restoration Angel, really love the card. Strong preference to the original art, even had it made as custom playmat.
I like the card. Last time I played it I cascaded into Time Walk. It turned out well for me Only real negative is the anti-synergy with counterspells. Also worth mentioning is the bonus that it is an artifact so it buffs Tolarian Academy, interacts with Tezzerets etc.
I already thought highly of this land, but it just got even better considering it is a great enabler for the Colorless required -cards out of Oath of the Gatewatch.
Very interesting set, considering it is a small set too. My 540 powered cube has a ton of cards to test, more than most large sets, which is super impressive. Of course, it remains to be seen, how well testing cards last. It will mainly hinge on how the colorless-only cards fair.
Finally got to play with this and unsurprisingly, it was awesome. Just one example: I was about to get milled, but had Time Spiral sitting on my 'yard and after that I felt like I couldn't lose anymore.
Just a side-note: I have found that it is sometime easier to find fixing for three color deck, than two color. Instead of just having one guild worth of fixing available to you, you now have three guild's fixing. In my experience, this usually means that light splash for 3rd doesn't require drafting fixing that much higher compared to two color deck.
Phyrexian Arena has gone underdrafted in our cube, maybe this planeswalker would be more exciting, but still fill that role. It helps that black planeswalkers are so shallow as a group. I only run Liliana of the Veil and Liliana Vess (well, also flip Lili if that counts).
I will most likely test this in place of Worn Powerstone. It does cost one extra, but it also gives you 2 mana the turn you cast it. Also one of the big problems with ramp decks is that when you have enough ramp, there are games that you only draw your ramp and not business spells. This will be awesome fallback in those situations.

For me, it was Unburial Rites, which was my 5th Orzhov card.
