Might of Gondor
Note: When I published this deck, I used an outdated version of the tactics deck. The more recent version (without ally Boromir can be found here: https://ringsdb.com/deck/view/139164
With a good start, both of these decks can put out a lot of combat power and resiliance very quickly and the Gondor synergy in each feeds the other very effectively. In particular, this fellowship shines in battle quests or any quest where the primary challenge comes from large numbers of enemies or from the number of enemies you must fight at the very start.
There are some notable weaknesses; neither deck generates that much willpower out the gate (though once visionary leaderhip hits this is no longer an issue), no location control, they have no treachery/shadow card cancel, low amounts of threat reduction and healing, and neither deck has reliable card draw so they can run out of steam (though Imrahil's ability does normally provide an effective 'extra feint' card per round).
On the other hand, with a bit of luck you can quickly find yourself with a massive board of buffed allies to leverage victory with and a comfortable safety net of events to help you resist misfortune or surges of resistance.
