so most of the cards have come from vintage tournament reports.

@JohnCJonesJr

I personally love the idea behind having a powered cube, that is specifically designed to feel more like vintage. My main dissatisfaction with regards to basically every powered list I’ve come across, is that they “tend” to play out more like amped up modern decks, and less like what Vintage and Legacy as a whole has encapsulated.

The one major thing I think your cube lacks, is copious amounts of mana rocks. It’s the first thing I look for in a good powered cube. I did some superficial math and would recommend 36 rocks for a 540 card cube. I also don’t see the point in drafting 4 packs of 15 and ending up with 37 sideboard cards. Also, I would cut time vault from the cube. The card is head and shoulders... just way too good. (unlike in vintage where it's fine) It just ruins games and will make players feel like they’ve wasted their time drafting.
