Battleship Cannon: BLUE

When Cannon: BLUE enters the battlefield
under your control, each player taps X untapped
permanents on their side of the field, where X
is the number of "Battleship" Artifacts you
control. Those permanents don't untap during
their owner's next untap step.
{u}{u}{t}: You may draw 1 card for every
opponent who tapped 3 or more permanents
this turn.
