MTG Salvation

The spike in me wants to throw Elesh norn, grand cenobite in every deck like this.

You don't need to throw much money at a mana base. Things like Dust bowl[ andStrip mine are cheap and fantastic with crucilble (Bonus points with Azusa, lost but seeking and Oracle of mul daya
Personal all stars for me are Academy rector (Finding Living plane or whatever you need). Also love Knight of the reliquary
When I did this I ran lots of cards like Cataclysm and Armageddon because I can ramp much faster than other decks and they're amazing with Crucible of the worlds and most importantly Life from the loam (There is no reason not to play loam in green)

It's pretty useful. The cards I mentioned are all under 20 and I figure if you have a crucible of worlds it shouldn't be too bad.
