Use skill is hard to define. If we go by the conventional, as in what I first understood it to be (hey look at me! I'm everyone!), "Using" a skill requires you spending quanta. Therefore, acceleration, vampire, and quanta generation do not count as using skills.
Why the need for a redundant ability? Why not just have it vanilla but have its first ability be passive?
If we do count vampire and acceleration and quanta generation as "using" skills, then this can get out of hand very quickly, with a +1/+1 to ALL your creatures EVERY turn. Slapping LS or accel on this isn't that hard either.
