4- Dance of Many
Secret Lair is also a place to put weird, older cards that would be difficult to reprint in a normal set. Dance of Many is one such weird, old card. It’s also one of the most playable cards that overtly references a dance.
3- Cyclonic Rift
This one is pretty loose, I’ll admit, but Cyclonic Rift shares its name with the iconic Rifts in Fortnite and is widely considered one of the best cards in some Magic formats. It’s also a highly demanded card, and we usually see a high-value card in a Secret Lair to entice people who need it for their decks.
