Sky Ray Gunship

Whenever a creature you control becomes tapped,
you may pay {1}. If you do, put a charge counter
on Sky Ray Gunship.
{t}: Remove X charge counters from Sky Ray
Gunship: it deals X damage to any target.
The Sky Ray can fire volleys of lethal seeker missiles
to obliterate its targets, often remotely fired by troops
with a markerlight device.
