MTG Salvation

I've played about 20 games with this deck on MO these days. What troubled me most is the mana base. With only 20 lands in the deck, it's usual to see only 1 land and Faithless looting in the openning hand. I thought they were keepable hands, but then I stuck to 1 land and lost quickly for 3-4 times. Any suggestion on that?

Leyline of the Void would be better than R.I.P. It only affects your opponents.

Has anyone tried with Thing In the Ice? In my testing, it is dominating against creature based decks like abzan company.
