With a 1st place finish with a record of 4-1, I am quite happy with my first run of the deck. I feel like the addition of to the deck was worth it. While Jace, Vryn's Prodigy
Flip and Serum Visions greatly help to make the deck more consistent at drawing threats and ensuring to hit land drops without getting flooded. That thing that is good at.
Narset Transcendent was intended for being extra card draw as well as a fun combo with Lingering Souls. If you flashback Lingering Souls with Narset's -2, you can stack the flashback trigger and rebound trigger so the rebound happens first. So when the flashback trigger looks to exile the card, it is already in exile. Then you get a free cast on your next turn thanks to rebound. You can keep this loop going so long as you can use Narset's
-2. While this is a fun gimmic, I actually sided out Narset Transcendent in every matchup. I feel like she is better served as a sideboard card over Notion Thief
While I also took Dragonlord Ojutai out each match. I still like having him in the main deck as a good closer that opponents will never expect out of a token deck.
With Narset Transcendent being relegated to the sideboard. I think I will be replacing her with one of the Timely Reinforcements(M12) from the sideboard. That card has definitely earned its keep for me in the past with my original BW deck Bitter Sorin - BW Tokens.
Now that Timely Reinforcements(M12) has gone to the main, I have room to add a Supreme Verdict to give the deck the wrath effect it needs against creature decks.
One last change I am considering is replacing both Relic of Progenitus with Rest in Peace like the BW version used. I realize this can be counter productive with Lingering Souls and Jace, Vryn's Prodigy
Flip but the ability to completely shut off graveyard decks has always been worth the hit I take in doing so. While these two cards are hindered, the deck still has plenty of power in Bitterblossom, Gideon, Ally of Zendikar, and Sorin, Solemn Visitor
