Just a quick explanation:
Been playing this deck since the new expedition season started and quickly climbed through gold and most of platinum with it. The idea is to splash Primal into the Give Chase shell to sacrifice some power stability for consistency in hitting your combo piece and game-winner, Give Chase.
The idea is to pitch an unleashed copy to a Whispering Wind to get a Give Chase. This means one of your best hits off of a Chase is a Whispering Wind + Unleash card to ensure that you can just do it again the following turn. The same can be said for Marauder - just try to pitch unleashed copies to essentially make these effects free. With Primal you also gain Plunk which is a staple for Expedition.
Enter the Arcanum really boosted the power of these archetype with the addition of Marauder and Ramcart - they really take the deck to the next level and allow you to be a solid, stable aggro deck even without the Give Chase at times. Good luck with the deck and let me know any changes you try out!
Cards I'd like to try still:
Collision Course
Reason: Inscribe cards are invaluable to the deck as is keeping board control. The taunt from collision course can be backbreaking so I wanted to try it out. Maybe in place of Jeering Yeti. Or perhaps a 2/2 split.
