I have been playing two decks for the past year or so. I am used to what their mana curves and average draw rates are. For the past few months, I have had a reproducible issue: if I start with a 2 land hand and play first, I will not draw any land for several turns. While I know that could just be odds, but I have been able to test and reproduce the issue. Again, this is most prominent in a deck I have played and not tweaked for years and is mono color black. Because of this, I am being forced to concede games by being hopelessly behind the curve. Again, it seems to consistently happen with a two land hand where I play first.
