After a number of games and a lot of frustration, I have determined that I had a lot of what the deck wanted but not what it needed. I added in some more mana ramp in the form of some land changes and some artifact additions. It felt as though I just couldn't get mana fast enough. With that in mind, I re-added
phyrexian altar. I also added
sword of the animist to experiment with in addition to
ancient tomb and
myriad landscape.
I also swapped out some creatures. I put back in Liliana flipwalker for her ultimate, even though I never managed to get her to it. I also added
bottle gnomes for guaranteed lifegain. I swapped
harvester of souls for
grim haruspex and also added
Feaster of Fools for a sac outlet and a possible flying wincon.
As an experiment, I added in
Kormus bell to turn my swamps into 1/1 creatures. I am not sure how it will fare as time goes on, but it could be a boon as my swamps couldd then be saced for effect and return at
the end of the turn.
