Raid — When Intrepid Captain enters the battlefield, if you attacked with a creature this turn, Intrepid Captain explores twice. (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 this creature, then put the card back or put it into your graveyard. Then repeat this process.)
deactivate, as it's hard to colour balance. it's a pity though as it's a great card.
