Missile Turret

Detector
As long as its not your turn Missile Turret
becomes a 2/4 Artifact Creature with Defender
and Reach.
"No Koprulu sector outpost is safe without a robust
anti-air defense system plus sensors to detect hidden attackers. In the Terran Missile Turret, you get both
in an inexpensive two-for-one deal."
