Magic the Gathering: Fblthp: Completely, Utterly, Totally Lost Secret Lair Drop Series [Traditional Foil Edition]

Have you seen our boy? He’s about two feet tall (maybe three depending on artist’s rendition); has one big, watery eye; answers to a name that sounds like someone blowing a raspberry? We hate the thought of him wandering the streets of Ravnica alone. Can you please take a look? We think he’s hidden somewhere in this Secret Lair drop…  

Yes, that’s right. It’s a five-card, Borderless panorama by Marija Tiurina, and it’s jam-packed with hidden Magic and Ravnica references. Please, can you find Fblthp on every card?
