I really like this deck a lot. It looks like it has great consistency, flows well, and looks like it would be a lot of fun to use. I've always liked using white, I think it's a fun color and I like the control certain cards like Pacifism and Oblivion Ring give you, and the life gain is always fun lol. I do, however, tend to advise against running single color decks, because it is so much easier for an opponent to hinder you if you do not have another color to fall back on, and mono white is sometimes difficult to pull off. Other than that, great deck!
