Tactics Imrahil competes for Gandalf as my favorite hero in this game, I love his ability and excitement that comes from using it every turn. I wanted to build a thematic deck with him, and someone on discord recommended Hirluin the Fair and to attempt and build an outland deck with him. And so, this is the result. I haven't tested the deck so far, but it was able to defeat Escape from Umbar, which says something for a deck that doesn't have healing. The general strategy of this deck will vary on your quest and if you are playing solo or multiplayer.
Ideally, you want in your starting hand a Prince of Dol Amroth to make sure you are going to be able to use Imrahil's ability to target all the allies in your deck. You are still running 10 allies that share printed traits with him, so, if you don't get this card in your mulligan, the ability still has a decent chance of triggering. A Heir of Mardil on him turn one ain't bad either, as with Denethor you are going to be able to trigger it consistently.
Depending on the quest, and if you are running Solo and have no help for questing, you might want to prioritize an Ethir Swordsman in hand as he contributes 3 out of the gate.
The rest of the decks kind of plays itself. Diligent Noble is there to provide Hirluin with the noble trait so he can receive resources from Denethor. It also replaces itself, which is excellent, and a good target in quests that discard your attachments. If Soldier of Dol Amroth is online than a Rod of the Steward is great on Imrahil to constantly draw cards. It also runs numerous cards for resource generation and smoothing. (Steward of Gondor would work wonders in this deck, but I try to play that cards as least as possible. Still, I left it in the sideboard for harder quests or for players that don't have an issue with it, just replace the 3 Wealth of Gondor.
All in all, a fun and slightly thematic deck to play.]
