Even variants of the same archetype can play in wildly different ways and this is such a deck
Its even flexible: Demonic Consultation and Tainted Pact can be tutors, and Thassa's Oracle works with about a thousand other combos
Of course, unlike those two, it'll never snipe a Titan, as the X is limited to the five colors of mana, but in tournament play, you're more than happy casting it for two or three
I especially like Scepter of Eternal Glory, a new mana rock that works as a cheaper Gilded Lotus for any mono-color deck, which is something Ill probably be interested in for other decks
