Yup I like the look of this one too - perhaps good enough if a five-colour shops deck ever raises from the ashes. I think the major bummer about it, is that it only gives you generic, not colourless mana. Would have been great for Shops decks to power out Eldrazi otherwise.
Maybe they still can, if they want access to the older titans that don't require strictly colourless.
@Water0 It. It doesnt help hugely - but what other deck would you put this in other than five-colour shops? It costs three to cast, needs lots of artefacts to be good and can only help cast non-artefact spells. Most non-artefact spells are coloured.
The alternative would be running it in a shops deck that wants to power out stuff like All is Dust, Karn Liberated or Ugin....now, that could be pretty fun!
