Oath of Lawn Guy

Enchant target creature or planeswalker.
Enchanted creature or planeswalker cannot attack or block, and their activated abilities can't
be activated as long as the controller of this card keeps an eye on it. (Keeping an eye on it refers to the act of watching the card, not actually placing your eye on it.)
"For the sake of my lawn, I will keep an eye on it. Wait, let me try that again."
