Alright...So considering OldTrees' idea of this creature using it's ability to protect itself, as well as the swift mechanic, the HP of this creature should be low.
I'm tempted to suggest higher attack power, to make this creature a fairly high priority target, even if the opponent is not concerned about the ability, possibly due to non-killing forms of creature control, such as

freezing, or

delay, or

RT (which acheives the same thing as bounce, ironically)
Some thing that I've just thought of is this: What would happen if a creature with bounce was targeted by the creature skill 'Devour'
