This color pair looks less focused than the rest, but does have a lot of token synergy to go wide against the opponent. The token payoffs are either mass pump spells or convoke spells that can take advantage of having lots of creatures lying around.

What's interesting to me is that outside of Kavu Primarch, green isn't really looking to just go bigger than the opponent unless you get to 7 mana for Pelakka Wurm. This means green needs to rely on synergy much more than it does in most sets where green is there to simply outmuscle the competition. There is some potential for ramp since GW already wants Eldrazi Spawn for the 0/1 bodies. Ulamog's Crusher is reasonable in this archetype for that reason, but is certainly not its focus.

GW looks like a snowballing archetype such that once it starts getting its tokens onto the battlefield it will be very hard to stop, but the deck is not all that fast. Slower decks will need to be prepared for GW's finisher spells and faster decks will need to keep GW off balance long enough before it gets going. I want to just briefly mention that thrive looks like it's in the set to enable GW but I'm not convinced that it will be good. It takes a ton of mana and needs a board state where GW is likely to be favored already, but I'm willing to be proven wrong.
