Carl

At the beginning of your upkeep, you may
look at the top card of your library. If it's an instant or sorcery card, you may cast it without paying its mana cost.

This is Carl the cheeseburger. He loves practical jokes and hanging out with his burger bros. When he was just a little mallow patty, he dreamt of one day being the funniest cheeseburger in the pack.
