I now track the Singleton...mostly Singleton foil basic lands I keep with my cube!
It was a pretty decent endeavor.
As of Aug 2021, the Cube has 239 unique land arts!
The card scans have been added back... don't have scans for NO and M* signatures yet, tho.
...or the damaged Deep Analysis.
For the first time in a long time, I'm up to date!
Monarch has been cut from the cube, due to NPE.
We'll see if it stays gone.
