I currently have two decks built for playing two-handed; one is spirit / leadership, the other is tactics with mostly Eagles as allies.
The spirit / leadership deck is mostly Rohan, which I like for it's theme, but also includes some Gondor like Faramir. I tell myself they are all Men, but still I would like it to be all Rohan. With Éowyn and Aragorn questing, I use the Eagles for defending them and the tactics heroes for slaying the remaining foul beasts.
I like the Elves and Istari the most, but my current collection doesn't seem fit for building a deck with them yet.
