As you might already have noticed, Primal Control decks have become viable once again on Expedition now that they have got a proper finisher in Sashenka. I have previously tried both the Hooru and Feln version, but ended up having the best results with this. Not saying that it is the best possible choice, but there is not very much solid relic removal in Hooru at the moment and Barbarian Guerillas
make up for it quite nicely. Also, I would much rather play Riva, Crimson Blur
rather than Feln's Blackmaw Carnosaur
anytime as it can still bring some value even if it eats a spot removal. Had to omit Boundless Knowledge
in favor of the other, better 4-drops. Eilyn, Hand of the Tempest
is very good againts other Primal control decks and Riva/Hive pumps it up!
