Loth-cat

Stealth, Sense
Stalk {3}{w} (As an additional cost, exile this card.
Target a Being or Creature card on the opponent's
field. Whenever they play another card with the same
name, or create a copy of the card, destroy both cards
and summon this card back to the field from exile.)
"Loth-cats can be vicious little hunters. If you corner
one, make sure to protect your face because that's
what they go for first."
