Two parter here. First, I'm replacing the Madness package with Landfall after Zendikar Rising upped the level of support at common. As much as I love Madness, it just wasn't deep enough and no one really wanted to draft it. Gruul has been a problem since the cube's inception and I'm hoping this rectifies that situation.
Second part, I'm adding 45 cards to the cube straight up. I want enough cards in the cube to be able to Glimpse Draft with 3 players. Any new cards from the last couple sets that I wanna test can get added straight in plus a couple cards that have just generally been on my mind.
I'm also considering replacing the Gainlands with the new Snow lands and finding room for Three Visits and Nature's Lore.
