Joseph, you have to keep in mind that there are differing amounts of Custom players out there. Some actually do this for fun, and just because an ability name you used is taken doesn't give you the right to claim it. You mentioned your Master Set had been in production for a month; these were posted in September 2011.
If you're going to make a lot more customs, check what has been posted already before filling in some ability names; they may be taken already.

The night's shadow exists, not sleeping at all,
The toil of the light is its only call,
Behind the scenes lurking with shadowy gall,
Its face never showing; height never too tall.
