Tailgate

The next time a creature enters under an opponent's control this turn, they also create a 1/1 Human Spy creature token named Corporate Spy that has "This creature can't attack or block"

So long as an opponent controls a creature named Corporate Spy, you may look at the top card of their library any time, you may play the top card of their library, and you may spend mana as though it were mana of any color to cast spells this way
"Could you scan me in? My hands are full"
