I could without a doubt live with 3
Wasteland, but I when I tried for a
Bojuka Bog I wasn't so sure of my choice. I'll try with a basic swamp, the cons for
Bojuka Bog were too numerous. I usually didn't want it in my opening since it came tapped, but by the time I felt ''ready'' to play it, the graveyard decks were already winning. And even with
Dark Confidant, I couldn't get it soon enough when I was already in need.
I also play 4x
Gatekeeper of Malakir. My list was outdated and wrong, I just edited it.
That being said, the reason I play both
Phyrexian Revoker and
Pithing Needle is rather simple; I just don't use them in the same match-up. I most likely won't bother with
Phyrexian Revoker vs Miracles, but despite what I wanted to believe, our Storm matches are beyond awful G1. Naming
Lion's Eye Diamond or
Lotus Petal saved me more than once on G2-3.
I also hear you about the sideboard. Mine isn't finished yet, but I tried to build it so I had varied options for the same problem. I have a few one-of in the deck, but I usually bring them with either more one-of or better packs of sideboard cards. The two flexible slot in my list are at the moment 2x
Contamination, and so far they've been doing wonder with
Engineered Plague &
Perish. The only match-up it where it wasn't enough was Merfolks because of their
Aether Vial, but I could usually deal with those with the ''normal'' sacrifice outlet.
I would be curious to see your sideboard for this, almost as much as I would love to get my hands on 2x
Chains of Mephistopheles. I might be blinded by fanaticism, but I'm sure this card is the solution vs Miracles and blue decks.
EDIT: Changes were made on the list, I DO run 4x Innocent Blood. It seems I copy pasted an outdated list at first.
