This MTG Secret Lair featuring Walking Dead characters like Rick, Negan, Daryl, and Glenn, was the first Universes Beyond product the company released, back in 2020, and at the time there was a lot of controversy about seeing TV actors depicted on Magic cards
Spells like Divination and Brainstorm are classic examples, providing you with more resources to work with immediately by increasing the size of your hand
Michiko Konda, Truth Seeker makes your opponents sacrifice permanents when a source they control deals damage to you, Saskia, the Unyielding serves as a form of player removal with dealing damage, Yidris, Maelstrom Wielder lets you cascade spells from your hand if he deals combat damage, and Gisela, Blade of Goldnight doubles damage to an opponent and halves damage dealt towards you
The lack of a 'once per turn' rider might make it too easy of a combo engine, but the design could be tweaked and balanced before receiving a proper paper printing.
Good luck
Its Ultra Rare rarity drives most of the premium over the set's regular cards
