Falko, Showoff Pilot

As long as a Spacecraft or Vehicle you control dealt combat damage to an opponent this turn, cards in your hand have spectacle. Their spectacle cost is equal to their mana cost minus . (You may cast a spell for its spectacle cost rather than its mana cost if an opponent lost life this turn.) Whenever you cast a spell for its spectacle cost, put a +1/+1 counter on Falko.
