hey, my friend has one like this, deck:your-life-ended-for-a-greater-cause you should compair notes
I actually have tried out Bloodline Keeper Flip , and maybe I didn't give it enough time / enough of a chance or maybe I just didn't have enough supporting vamps to transform it quick enough, but I just felt that it was too slow to be as effective as I wanted. With Vampire Nighthawk and Sorin in the deck now, however, I think I will try the Keeper out again, and hopefully this time I'll be able to make the most out of it. And actually, as much as I love Skirsdag High Priest and want to make it work, it's also a little slow and takes a few turns / resources to do its thing, so I'll probably replace it with Blood Artist when testing out Bloodline Keeper Flip . Good call!
