Maybe it's just me, but I never really felt there was much too get excited about Helm's Deep. The standout cards to me were Gamling, Grima, Slinker and Stinker and you've pulled them. I guess Alcarin and Grishnakh would be nice, but there is a whole load more cards to open
A foil copy of
Grishnakh, Orc Captain and
Sting, Baggins Heirloom are probably the two best cards from that set from a collector's value.
From a player's perspective, there are several cards and strategies that Helm's Deep introduces that were amazing [particularly in Towers Block]. The addition of
Gollum, Stinker made Easterlings more potent, and new machines added another wrinkle to Uruk Archers.
Mumak were introduced to Southrons--still the weakest Shadow side in Towers Block--and the basis for Knight strategies were founded here.
Arrow-Slits and a handful of
possessions are still commonly seen in competitive decks, and
Grishnakh, Orc Captain and
Orc Patrol changed the way that Sauron could be played. Pre-skirmish wounding was expanded with
Baruk Khazad,
Fury of the White Rider, and
Rohirrim Bow,
Just some thoughts about the set.
