Cruiser

Sailors get +1/+1 for each Cruiser in play.
Battleships, Cruisers, and Destroyers power and
toughness are equal to the number of sailors and
Commanders attached to it.
When Battleships, Cruisers, and Destroyers are
destroyed, all Sailors and Commanders attached
are destroyed unless you pay {u} for each Sailor
and {2}{u} for each Commander.
Cruisers have protection from damage 3 or less.
Attach only 1 Captain and up to 5 Sailors.
