Captain Kathryn Janeway is a mythic Legendary Creature — Human Officer card from Star Trek (TRK), collector number 386.
You may play an additional land on each of your turns. Whenever Captain Janeway or another creature you control enters, that creature explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on the creature, then put the card back or put it into your graveyard.)
