Koloth, Tribble Hunter is a rare Legendary Creature — Klingon Warrior Officer card from Star Trek Commander (TRC), collector number 289.
At the beginning of your end step, each player creates two 1/1 white Tribble creature tokens with "This token can't block." All Tribbles get +1/+0 and are goaded. (They attack each combat if able and attack a player other than you if able.)
