Islandwalk (This creature can't be blocked as long as defending player controls an Island.)
Whenever Adrestia attacks, if an Assassin crewed it this turn, draw a card. Adrestia becomes an Assassin in addition to its other types until end of turn.
Crew 1
Adrestia’s second ability will trigger only if it was crewed this turn by a creature that was an Assassin when it was tapped to pay the cost of Adrestia’s crew ability.
