I think theyre so fun (I mean, I made a Chappell Roan-themed token deck for the Pride event this year)
In this set (and in Evolutions, which I analyzed the same way) cards are inserted from two sheets of uncommons into packs alternatingly, yielding two sequences of 54 uncommons each, making it relatively easy to reconstruct the uncommons sheet with the data from just a small number of boxes (3 in this case)
Varina won't be our only way to generate zombie creature tokens
Together, these cards form an infinite loop: you sacrifice Familiar to Seer, drain your opponent, then use Samwise Gamgee's Food token to bring Familiar back, repeating the process until the opponent is out of life
Hidden Courtyard, Hidden Cataract, Hidden Necropolis, Hidden Nursery, and Hidden Volcano make up a cycle of mono-colored caves that all give you an option to sacrifice them to discover 4
You can immediately capitalize on this with legends that sacrifice themselves, like Boromir, Warden of the Tower or Sidisi, Undead Vizier
