It's much better with four martyr and four proc. What does Flagstones do for you?
I'm not so sure about Cloudshift , but I do agree with regalrecaller. Kabira Crossroads ought suit you better. Some cards that I really like for lifegain that I have in my own deck (Gainin' Life, Likkabaus) are Cradle of Vitality and Boon Reflection . Definitely +1 for the Soul Sisters though, played this hard when it was standard.
Flagstones will thin the deck thanks to the Legendary rule.I like the idea of 4 Martyrs and 4 proclamation of rebirth, but I'm not exactly hooked on Cloudshift. I mean, it could save an Ascendant, but.. I could cut the Zeniths for 3 Martyrs and 1 proclamation, how does that sound?
Kabira Crossroads could work, but I don't like them coming into play tapped.Thanks for the comments guys!
