NOTE: Feel free to replace "60 cost" with "min cost" if it's a spoiler

I got fairly close to a true min cost, but ultimately gave up and made this. With 60 cost, I got 3 gold, 3 silver, and 2 quicksilver, but with only one access point on a bonder, I just barely couldn't get the whole thing built. 

Instead, I made this, which I believe is the lowest possible cost while also leaving no waste. I'm not entirely sure about that, but I enjoyed making it, and it was a nice cooldown from the frustration of not making an actual min cost solution.

I'm so excited to see the wizards that figured out 60g, I'm sure someone solved it.

Enjoy
