The size of the deck is where I ran into problems when I tried to build it as well. You absolutely need a cycling engine, maybe even multiple ones.
Woodhall Elf could be one. Horn filter if you are okay with everyone talking smack on GEMP.
HKOTN is also an option, but imo way worse than horn when it comes to NPE (horn is fast...
HKOTN is slow and does it each regroup). I really enjoyed a
Ship of Smoke build lately, it is amazing at cycling but runs the risk of discarding
Alive and Unspoiled.
Gloin, SOG was my initial thought for the deck with Gamling pulling a Doorwarden for him to become a mini Durin.
There are a bunch of orcs you could try as one ofs.
Black Land Chieftain for one,
Chamber Patrol etc.
