Maestros Confluence Versatility is the name of the game with Maestros Confluence
Feeling less like a zombie-tribal deck and more like a giant token build, I think your average Geralf deck probably benefits from some unblockable synergies with cards like Thassa, God of the Sea or Deepchannel Mentor
Its also a piece of Urza, Planeswalker, a Melded planeswalker card created by Urza, Lord Protector, and The Mightstone and the Weakstone Artifact Melding together
Choking hazard
In my experience though, the top card is usually Zetalpa, Primal Dawn
Its also a good creature as a 3/5 with deathtouch and lifelink, which is a creature that stands on its own, but its vulnerable to a large amount of creature removal
