Immobilize with Gold 2W
Enchantment - Aura
Enchanted permanent can't attack, block, or crew Vehicles, and can't activate its abilities unless they are mana abilities. "Intruders will be melted." -Axgard inscription
It's Vehicle-proof Arrest that affects all permanents. . . but because it's White it's immediately considered garbage.
As for the card - this is good. It does all that people have pointed out and it also stops planeswalkers! Pacifism-style effects have been weaker in limited environments lately, but this is still probably one of white's best commons.
