1) Dragons - played as super intelligent with long term motives makes for great villians.
2) Liches - again with the long term motives.... preferrably 20th level +
3) Succubus (bi?) - ultimate teasers...
4) Slaad - the randomness of individual monsters frequently leaves the party guessing...
5) Drow - conniving, plotting, need I say more?

The text of the power says:

Your skin and equipment take on the color and texture of nearby objects, including floors and walls. You receive a +10 enhancement bonus on Hide checks.

The first part is flavor text. The rules text (and only benefit from this power) is that you gain a +10 enhancement bonus on hide checks.
