I finally got to play my first game with the mountain king last night. It was against a friend that plays another game mainly but plays Hordes every now and then. Not doing a full battle report, just some highlights with my experience with him.
My opponent ran a T4 Baranabus list
Mangler (Not sure on the name, the small gator with the spiny growth animus?)
2x min unit gator posse
Full unit gator posse
2x croak hunters
min bog trogs
I ran Borka
Full Fenns w/ UA
Full KSB w/ UA
Sons of Bragg
I went first and ran into position with the fenns, KSB, fell caller and Borka fairly central with the king slightly to the right flank and the Mauler and SoB slightly to the left flank. Fenns ran up to do their thing and screened the mountain king from attacks. On the turn I engaged the Fenns charged in, killed the 2 croak hunters and a couple of posse and wounded a couple more.
His next turn he wiped out pretty much all of my fennblades with his posse and a wrastler and regrouped his battlegroup just trying to avoid the mountain king. My next turn I actually did some pretty cool stuff. I activated Borka and cast Mosh pit. I had the fennblade that was close to a wrastler hit it just to knock it down. I then walked up the Mauler, threw up his animus and proceeded to chain attack the knocked down wrastler and threw him at Barnabas, hitting him and knocking down a couple of other models along the way. Next I activated the mountain king, threw up his animus and slammed my remaining fennblade that was engaged by the posse. I killed a few models and aimed my killshot at Barnabus hitting a pile of stuff that was knocked down from the throw including Barnabus. I then proceeded to sweep through the remaining posse and kill them all.
We called the game at this point because it was getting late and I had wiped out all of his posse, all of his beasts were dead or only had a couple of boxes left. It probably wasn't the best test for the king's true potential as he was a fairly new player to the game but I can see some of his merits. Kill shot can be nasty, I know his MAT and RAT are really low, but knocking stuff down with power attacks and mosh pit from Borka can really off set that.
I'm going to have to try to bring him out against a more seasoned player and see how he holds up. I'm pretty happy with the list. Sons of Bragg didn't get to do a whole lot this game, but they did pretty much trash a wrastler in one turn. I find that Borka synergizes fairly well with the king due to his feat and mosh pit being able to knock stuff down so the king can hit easier. Even if the mountain king isn't getting the best response from the community, it is still a great feeling seeing that big painted guy on the field of battle.
