I have a question that came up in my cheapo commander deck. With a flipped Kitsune Mystic / Autumn-Tail, Kitsune Sage and a Sun Clasp under your control, If you move the Sun Clasp to your opponent's creature, activate the clasp, and respond to the ability by moving it back to your permanent what will the result be. Based on the wording and the fact there are no rulings on the Clasp I don't know if the card bounced will be the creature it was attached to when activated or the one it ended up on.

When the ability of Sun Clasp resolves it does as instructed. It returns the ENCHANTED creature to its owner's hand. The enchanted creature is whichever creature the Clasp is currently on when the ability resolves, not whatever creature the Sun Clasp might happened to have been on when the ability was activated.
So in your scenario, you would end up bouncing your own creature, not your opponents.
Sun Clasp's last ability refers to the creature it's currently attached to (or was last attached to if it's no longer on the battlefield) when the ability resolves (and it's that creature that's returned to its owner's hand), regardless of what Sun Clasp was attached to when that ability was activated (C.R. 303.4k, 608.2g).

The enchanted creature is whichever creature the Clasp is currently on when the ability resolves, not whatever creature the Sun Clasp might happened to have been on when the ability was activated.

Hope that helps.
