4x Viscera Seer: This may seem peculiar at first but have 4 of these guys is pretty crucial to the decks functionality. Getting a sac outlet for revolt and other shenanigans on turn 1 is super sweet and it allows us to filter through our draws for the rest of the game.
4x Satyr Wayfinder: The other key piece to the deck, this guy does everything you want in a Seance list. He digs, hits land drops and comes back from the grave for more value.
3x Tidehollow Sculler: This guy is fantastic, he allows our deck to find cards that hurt our strategy early and remove them before they become an issue. It is also fantastic with all of our sac outlets, because we can sacrifice him in response to his ETB, making his second ability trigger first, thereby permanently exiling the card we pick from their hand, and triggering revolt at the same time. He also works well from the graveyard when Seanced as long as you have a sac outlet too.
3x Renegade Rallier: An all-star in our deck, rallier is like a mini seance that can be recurred with seance! He does it all, wether it be ramping, getting back a wayfinder to dig, getting back a sculler for more hand disruption or getting back one of many of our sideboard cards. Hes also one of the better bodies in our deck, so he attacks pretty well too.
2x Eternal Witness: A fantastic card that can recur some of the cards that seance can't. We also are going to be milling seance sometimes with wayfinder, or maybe we really need another removal spell. In those cases, eternal witness really comes in clutch.
3x Siege Rhino: A fantastic body for the cost of the card, the rhino really helps us close out games. You can play him and get a 6 point life swing, and every time you seance one back its another 6 point life swing.
1x card:Shreikmaw: Its nice to have creature removal in creature form, for its obvious synergy with seance. The reason I am not playing more is that a lot of the best creatures in modern currently are black or artifacts.
1x Pack Rat: Nobody sees this card coming and it is another great way to close out a game. In addition, it synergizes well with seance in that you can use its ability after it has been seanced to get a permanent rat back on the field, and the ability itself is good iwth graveyard decks in general.
