Thicket of Spears is a highly under-rated card. It's caveat turns some players off, but it's never been an issue for me. In enemy heavy quests like helm's deep and Bo5A, this card works wonders. If you want to break the game, you could put this in a mono tactics Hama deck and quest with your other two heroes every round, not having to worry about enemies.
Thicket of Spears
You must use resources from 3 different heroes' pools to pay for this card.
Action: Choose a player. That player's engaged enemies cannot attack that player this phase.
The Two Towers
Core Set #36. Tactics.
This card is even better then Stand Together in heavy enemy quest. If you have enough resources, you will not waste any action to stop a horde of orcs. Yes, for using it, you need three different resource pools, however i don't think you're limited to mono - tactics decks. If you're using Song of Battle for some reason or attachments like Narvi's Belt, consider to add this card to your deck, it can do miracles in nasty enemy quest. Artwork is excellent and adequate. Verdict: 4/5.
