Island Fish Jasconius (3ED #61) is a rare Creature — Fish from Revised Edition. It has an upkeep-triggered ability allowing you to pay three blue mana to untap it and it won’t untap during your untap step otherwise. It cannot attack unless an opponent controls an Island and must be sacrificed if you control no Islands, creating strong deck-building constraints and synergies around opponent lands and your island count.
