MTG Salvation

I have been messing around with the idea of a RWb token attrition deck. The threats are aggressive and work together to spew out tokens and prowess triggers.
Mardu has just about the best spell package options in modern with bolt, path, and discard spells.
I am looking for input from others to help improve the deck and see where to go with it.

This is a deck that did well.

This is what I've been jamming these last few weeks. Currently 18-12 in the friendly leagues on MOTO. I really like that mtgtop8 list posted above, but I can't imagine running 75 cards without Dark Confidant

Painful Truths does a good Dark Confidant impression. Why Wrath of God over Hour of Reckoning?

I think the Monastery Swiftspear is best in an aggro deck trying to push through quick damage (with Delver of Secrets and Stormchaser Mage, possibly splashing white for Path to Exile and Lightning Helix). Young Pyromancer/Lingering Souls is more of a value deck - I would then include Monastery Mentor and Nahiri (or leave out Nahiri package and run Dark Confidant).
