So the number crunchers listed the odds of getting the "good card" insert is about 1: 720 packs. That's not particularly high. That's 1 in 20 boxes.

One thing I did learn from the midnight prerelease I went to. Green/White is really strong. Allies are amazing. Removal is at a premium if you aren't playing black. Almost all the rares are playable. I went 3-1 and got 6 extra packs. I'm happy. Foil Arid Mesa and Foil Mindbreak Trap (sold for $50 before I left the store ).

Yeah, play green white. It's good.
