So, looking at Saffron Olive’s original list, we’ve lost a few cards, but not that many. Disperse can be easily replaced with cards that are strictly better, such as Compelling Deterrence, but Mage-Ring Network is a bit more problematic. Having played the deck some, it feels like a big loss.
On the other hand, there’s a number of cards with cycling, which could potentially be very good. As Foretold can replace the Brain in a Jar, especially in an environment with rampant artifact desctruction. Mix of both might also be a good idea.
Sadly, Engulf the Shore want be very good in many spots, because of the high toughness of many creatures, especially in the BG decks, but this is more of a fun deck than an actual competitor.
