Interesting if you have something with "when a
creature comes into play" effect. More for the
casual fun deck builder. In limited, you'll see
this guy stalking the board on occasion,
bouncing in and out of play.

Sandstalker - I've always thought that the
sandstalker's self-bouncing ability (later seen
on Viashino Cutthroat and Glitterfang, among
others) was one of the most interesting
abilities ever featured on a creature. There's a
lot of levels to it. At first it seems like a
drawback, as you have to recast it every turn.
But there's a couple good sides. First, it
dodges your opponent's sorcery-speed removal.
When you're playing against someone that relies
on Wrath of God, that matters a lot. Second, it
lets it come into play multiple times. This
didn't matter much until Glitterfang allowed you
to take advantage of "spiritcraft" triggers
every turn. Sandstalker is with us in 9th
edition, and pleasantly so.
