They really should set a buy back sphere option in the acheivements reward corner.

Makes them check ur inventory if 1 unique sphere exists or not given by arena if it exists, the sphere is greyed out, else, it lets you buy the sphere for 2x the original merit sales price. This is to let players get the sphere they sold not knowing that they are useful in the future.
