- Prince Imrahil & Keen-Eyed Took
That must be Sneak Attack + Gandalf (Core). It is from day one.
To gain Sentinel or help in combat when a shadow card comes up that you can't otherwise deal with… (2+ player games)
Sneak Attack + Landroval
Sneak Attack + Gandalf (core) [destroy the attacker]
Sneak Attack + Landroval + Brok Ironfist
Bofur (spirit) + Prince Imrahil
Errand Rider + Elrond
We Are Not Idle + Lure of Moria [probably one of the easiest and potentially one of the best with 5+ Dwarves]
Hmm, with one I forgot, we got 4 common combos, surely there are more?
Born Aloft + Gandalf/ Descendant of Thorondor/
Legolas + Blade of Gondolin (3 progress tokens)
Glorfindel + Asfaloth + Light of Valinor
Arwen Undomiel + Boromir (core) - sentinel and multi defender
Gildor Inglorion + Zigil Miner
Glóin + Warden of Healing
Gondorian Spearman + Spear of the Citadel
Rivendell Blade + Legolas
Thalin + Gondorian Spearman
Thror's Map + Asfaloth/Northern Tracker
Thalin + [any weapon] + Gondorian Spearman + Spear of the Citadel + Goblin Cleaver
it looks like a five card combo, but it is not hard to pull
Elrond + Warden of Healing
Hama + Feint / Thicket of Spears
Elrond + Vilya + Imladris Stargazer/Gildor Inglorion + expensive stuff
Hama + Feint (not really a combo…)
Trollshaw Scout + Rivendell Blade + Foehammer: generates cards to fuel his attacks, & he has ranged to attack anyone. Add Hama to recover the Foe Hammers & Hands Upon the Bow to do it out of turn.
Beorn & Fortune or Fate - the only hero you might plan to lose. Horn of Gondor to mitigate the cost …
Denethor and any attachment that allows him to ready (After seeing the encounter deck) to defend.
A few really basic ones…
Beravor + Unexpected Courage ("Free" draw)
Gimli + Citadel Plate + Boots From Erebor (Obvious, but great)
Thalin + Celebrian's Stone (It feels like you always want him to quest, so let's make it even more worthwhile)
Song of Wisdom + A Burning Brand (Make anyone able to use the former)
EDIT: SORRY FOR THE FORMATTING! POSTING ON MY PHONE STINKS!
Weapon Attachments + Foe-Hammer or Goblin-Cleaver = killing enemies or card draw.
Thalin + Expecting Mischief = Useful to soften enemies or kill them at once.
Fili and Kili + A very Good Tale = pay for one brother, get the other and use AvGT to potentially pull 2 more allies ending with 4 allies with only 3 cost of resources.
Expecting Mischief + Goblin-Cleaver = perhaps not very common but i discovered it by accident. EM dealt 2 damage to an Orc Vanguard (from HoN). Later in combat had many enemies and G-C helped deal the remaining 3 damage to kill it.
Gandalf (Core) & A Very Good Tale & Another Ally & an ally packed deck (20+,25 best) - Gandalf readies in the refresh phase just before he disappears so using him then for AVGT is "free".
