Progression 3: Conflict at the Carrock (with Challenges!)

I've been busy for a while, but it is now time for part 3 of the Progression Series! Last time, I took down The Hunt for Gollum and managed to pull off both of the challenges. (For more information on that see here: https://ringsdb.com/fellowship/view/11168/progression2thehuntforgollumwithchallenges)

This time, I will be attempting to beat Conflict at the Carrock while also achieving a few challenges. To see the full rules for my progression series see the first fellowship here: https://ringsdb.com/fellowship/view/11104/progression1thecoreset

Today's challenges, courtesy of Truck:

1: Start off with a copy of Sacked! on top of the encounter deck

2: Be engaged with all four unique Trolls at once (The Trolls can be engaged with multiple players, they all must simply be engaged at one time)

3: Get Grimbeorn up to ten resources.

Please feel free to leave any comment or challenge suggestion for the next scenario, as I tackle a Journey to Rhosgobel!
