Snail infestation

Snail infestation may only enchant a vehicle
that is controlled by an opponent.
Whenever enchanted vehicle becomes crewed it
loses all its abilities and you create X 0/1 blue
snail creature tokens where X is equal to the
enchanted vehicles toughness.

out and see yourself what has happened to our ship."
