MTG : Rocket Launcher - (Antiquities) - U (SPLD+)

Artifact

{2}: Rocket Launcher deals 1 damage to any target. Destroy Rocket Launcher at the beginning of the next end step. Activate only if you’ve controlled Rocket Launcher continuously since the beginning of your most recent turn.

What these devices lacked in subtlety, they made up in strength.
