[3.5] Tricksy Little Halfling Build Help

[The Bandicoot]

So a campaign I'm going to be running calls for an epic leveled planar/reality traveler. The way I was thinking of going was bard 14 for the spell Shadow Step so he can travel between the planes/realities and then horizon walker 10 more for the fluff.

This guy isn't going to be a big enemy or ally to the group, just more of an interesting encounter.

So playgrounders, how would you build a tricky prank-loving halfling who travels the planes and realities?

Edit: sorry for not putting this in earlier but by epic level I mean anywhere from level 20 to level 30

If he's pranking the party, he needs more defensive abilities. ToB characters can do that, so can tier 1-2 types. Bards risk turning into a red mist ~6 seconds after the party gets sufficiently irritated.

If he's pranking their enemies or neutrals your build sounds fine to me.
