obsequent: flowing in opposite direction to original slope of land (also, and unlisted: yielding, submissive, obsequious) jersey: plain weft-knitted fabric of wool, cotton, nylon or silk (also unlisted: that island)

Because that definition doesn't make much sense - it's basically a switchback in a stream. Say you have a drainage basin that's sloped to the sea to the east. The big river then runs mostly W->E ish. But at some point there's a tributary that runs E->W ish to join it. That's obsequent. And... well, I'm unsure that geography is a useful thing to put into a magic card :)

Still. "It goes the opposite direction you expect" is a wide enough concept that we could use. But "Jersey"? How'm I gonna get that into a card? Well, sheep maybe? Magic has a couple of sheepie cards already.

So a sheep that goes the wrong way. Ah, a sheep that rounds up dogs. ... huh, I fail to find appropriate art. I admit to not trying too hard.
