Play only before the staging step.

Fey he seemed, or the battle-fury of his fathers ran like new fire in his veins...

Finally, a single card that makes hero treebeard really good. Attack for 7 and quest for 6 in a single action. It can be hard to find a spirit resource when playing an Ent deck, however.

You could splash in a couple Songs of Travel. — eddyvan 34
Could also play in a Fellowship with a deck that has Spirit access. — Diamondore12 27
The biggest problem is that you need to have an *eligible* enemy, which for hero Treebeard means an engaged enemy. That means the enemy either has to be one that starts engaged with you on Turn 1 (a few quests) or that you engaged during the planning phase (e.g. with a Westfold Outrider). Otherwise, you're just dealing with an enemy that you weren't able to kill the previous turn. So I think that makes this combo even more niche, on top of the need to combine Lore, Tactics, and Spirit. — kjeld 663
