Impounding Lot-Bot

When this creature enters, you may say "INCARCERATE!" in a robot voice. If you do, exile another target artifact or enchantment until this creature leaves the battlefield.

If Impounding Lot-Bot leaves the battlefield before its enters-the-battlefield ability resolves, the target artifact or enchantment won’t be exiled, even if you say INCARCERATE! You should say it anyway though.

There are many different kinds of robots, so you can determine what “robot voice” means to you, though it should probably sound different from your regular voice (unless you’re a robot, I suppose, in which case I for one welcome our new robot overlords).
