Coiling Oracle wasn't really doing much. Hopefully, by replacing it with Lonis, we get a bit more bang for buck.

Roar of the Wurm was simply a victim of creating a unique token, which I'm trying to tone down on. Replacing it with another creature that makes a clue instead makes token complexity a little lower.

For much of the same reason, Bastion is gone. Vampiric Tutor is a good card that allows redundancy to find your pocket of synergy easier, but at the cost of a card.

Ulvenwald Hydra was a boring card that nobody really cared about. Rhonas is a much more exciting (and dangerous!) card. Maybe it can be a seed for a power 4 matters synergy later.

Too many Goblins! Now that the cube was cut to 450, there are too many cards that generate goblin tokens. The 3 drop slot is a little crowded, especially for gobbos, so dropping goblin assault, one of the weaker token makers, made sense here. Gamble is a nice little card that allows redundancy in the pockets of synergy, but, again, at a net negative of a card. On the upside though, there are discard strategies that may be able to make use of it.
