Simple Q&A D&D 3.5 (by RAW) XXII

A21
If by "is effectively a" you mean "counts as a" for purposes of enhanceability, damage reduction, etc. ...then no. It might function identically, but it doesn't have the "this sword is a magic sword" tag which enables it to do all the things which a +1 sword can do.

Q22
Is there a playable (ie not "LA: --") race of Construct, Ooze or Magical Beast with one or more HD? I'd prefer the LA to be as low as possible, and the HD to be low-ish (somewhere from 3 to 7 or so).
EDIT: Okay, the Aranea is one example. I'd like to know if there are others.
EDIT2: Forgot to specify, it has to be Large or larger.
