I like it

I haven't made a T2 deck yet, as I'm just back in the business after a 3 year-break, but I looks cool. I've always loved white-weenie

I don't know if Oblivion ring works well, but I'm not all that impressed by it when I look at it...Maybe some other cards might be better?
EDIT: I made a T2 deck with MWS based on your deck, but I've changed some things. I play a Hetid Heath 3x and 4x Caves of Koilos and 4 shriekmaw for some extra control...The biggest sucker to play against is Chameleon...he rapes me...any ideas against him? -> Most of the time I use crib...
EDIT2: I think the black twist really helps...for Nip, Stillmoon, Divinity and so on, it doesn't matter whether I use plains/swamps...and the 1 damage of koilos is largely compensated by the lifelinkers (Nip, Meadow, Divinity)
