My sideboard starts with a pif just because I always want access to it and that makes 8 effective copies between gamble, burning wish, and the 3 others.
If I have a lot for the match up I will usually go down to 2 pif.
Went 2-2 at my lgs today, beating D&T and Maverick, losing to UR Delver and Czech Pile. Hate bear match ups feel a lot better with 3 sulfur elemental in the side.
UR Delver came down to a bad reforge the soul and a bad gamble, variance happens. I've played the match up a lot and I am otherwise confident in it.
It felt like 4 color control was strong against the deck. It has a lot of answers early enough that even a fast blood moon isn't sufficient. Has any one else has luck with the match up?
I have been inspired to make room for guttersnipes in the main to mitigate the BUG/4c control match up. The incremental value seems worth it ultimately. I just wish that it didn't open up creature removal which is dead for my opp. otherwise.
