Reinforced self mill
Removed artifact archetype, added spells (izzet)
General updates etc.

Switched cards around to remove boring picks and put more exciting ones instead. Added some more support to the weaker archetypes like aristocrats and self-mill.

Changing some cards for other cards with more interesting play patterns, or who are desirable for more decks

Triplicate titan is easier to cast, and better suited to cheating strategies, as well as ramp strategies, where Sphinx was almost exclusively a reanimation target.
