I've been playing a bunch of the most recent iteration of the Tinkerer's Cube on MTG Arena lately and I've really been loving it.
For those who don't know, it is a low-powered historic cube and uses learn/lesson cards from Strixhaven as a theme.
I've liked the cube so much that I've been looking into building my own cube based on it. The only thing about the cube that annoys me is the fact that it uses 4 copies of Environmental Sciences. I'm a singleton purist, so that won't fly for me.
So, do people think that learn/lesson as an archetype would be viable in a singleton low-powered 540 cube or is it too anemic? I realize cube context matters, but I don't want to build a "weak" cube. If vintage cube is a 10, I guess I'm aming for 6.5.
