I originally would have said every YuXin cube, because even though they're not known for their speedcubes, they have big cubes like the 17x17 that normally cost a lot. But, they also have a lot of normal things like 2x2s and 3x3s that I don't really need. So I'd go with option A, and REALLY take advantage of it by getting really expensive cubes like the 17x17.I'd rather be Feliks Zemdegs because it must be hard for Max to be autistic and I don't think I would enjoy having a difficult time communicating with people. Nothing against autism here, I have a bit of Asperger but I just wouldn't really enjoy the difficulty of communicating with people if I had autism.
A. Get three cubes (any cube) for free
B. Get every single Yuxin cube that exists right now.
A. Go forward 10 years to see what cubing will be like then
B. Go back in time 10 years to see what cubing was like back then
