The prompt for this was, "what is safe to put in blue with top swap". I... don't think this is the answer, really. It can blank removal, and can help you get value out of your etb creatures. That's pretty neat, but maybe it does nothing unless it is comboing?

Top Swap means this'll be available for the player casting it essentially every turn. Maybe that blanks removal too well? Discourages trying to interact because your opponent will just bounce their thing? I'll have to think about it.

Kicker is to just experiment with having additional effects on kicker with this mechanic. Maybe what we do instead, is to have one effect like Surveil or somesuch, and the kicker returns a permanent they control to its owner's hand?

Is it clear that you could bounce a permanent, and then use the Top Swap bottoming effect to bottom the card you pick up? Is that interesting or useful?
