Thorin is often overlooked these days for his cousin Dáin Ironfoot whom is arguably the lynchpin of any Dwarf deck. However unlike his cousin he comes with high as standard and in built resource generation. Something few heroes do.
Thorin really shines when paired with other Dwarves such as Ori and Bombur. Where Dáin Ironfoot rouses all Dwarves as the current King Under the Mountain. It was arguably Thorin who put him where he is, utilizing nothing but toymakers and a handful of less than warriors. Restoring the Dwarves to their former riches and that is shown perfectly in his card design.
Before you goto the staple that is Dáin Ironfoot give Thorin a thought. His card design is simple and effective and as Tolkien said "It is no bad thing to celebrate a simple life."
