The two most interesting cards in the set to me are Davriel, Soul Broker and Tome of the Infinite
In general we won't ditch the main idea of a deck and will stick to using Commanders available in the deck
Rin and Seri, Inseparable Jetmir, Nexus of Revels Jinnie Fay, Jetmir's Second Anointed Procession Sol Ring The deck includes 3 reversible borderless display commanders printed on a thicker cardstock (great for showing off your commander but not legal in sanctioned play) as well as 10 Plains, 5 Mountains, and 7 Forests for a total of 22 traditional foil basic lands with new art
The borderless copies of Summon: Knights of Round follow the same pattern
The sacrifice ability occasionally came in handy, guarding against mass removal even though it was never the primary motivating factor, and it was hard for decks running him to justify keeping the necessary mana untapped until very late in the game
This puts the deck over the top with removal or player kill too
