I would suggest Norn's Annex and maybe Ensnaring Bridge . You might also reconsider your decision not to attack with a Atraxa. If you put in Guildmages' Forum and Opal Palace , you can cast Atraxa with a counter(s) on her and proliferate them. Swinging with a big lifelink creature every turn gives you health to fuel a Necropotence too. Duneblast and Divine Reckoning would give you boardwipes that leave Atraxa in play.

xSindrix: I do like most of your ideas. I had thought about the ghostly prison effects for this deck as I do have pretty much all the cards that have that ability. The reason I didn’t though is I found the fog effects which have won me numerous games. I am definitely gonna find room for those boardwipes you mentioned. Also, I had played the play style I described for so long I forgot about the lifelink she has lol. That could have helped me on the games I have lost with her lol.

I'm revamping my girlfriend's +1/+1 Atraxa Deck into a WAR-ready SUPERFRIENDS, and I was wondering how this build was faring for you so far?

Wicker: I’ve only just started acquiring the cards from spark so I haven’t really tested it with them in it yet. But I can say that I win a lot more than I lose with it in its current form and the spark cards added to this list will only enhance it as far as I can tell.
