It feels like the majority of Expedition players are on some form of Feln right now, so I created this deck to work around their removal and Heron game plan. It is loaded up with early game Aegis units to counter their cheap removal spells, and then it includes both Reinforced Reaper and Reusable Femur for answers to Heron.
Ideal play pattern is Warrenborn Mistral, into Quinn, and then a versatile weapon onto Quinn, giving the extra buff to Mistral or Quinn depending on what you are facing. If you are playing against a non-Feln deck any versatile weapon can be played onto Quinn, but against Feln you should hold Reaper and Femur for the inevitable Heron.
Update: Some small changes for the month of October, mainly to increase the number of units. I was able to reach Rank 1 again with this current version of the deck.
P.s. I'm not sure about Murgo in this deck.
