Ahh, Entangle, about the only non-Spell Compendium Ranger spell worth a damn in 3.5. Somehow, I think that spell could be picked up by a Cleric Training feat, and then you move on.
Also, I'd have to say that the Spell Compendium presents a bit of irony. It's the book that gave Rangers useful spells in 3.5, yes. But take a look at what all those SC Rangers spells were. Arrow Mind, Arrow Storm, Blade Storm, Hunter's Mercy, Find the Gap, etc., ... those certainly did not have a "nature-related" vibe about them.
In fact, those "spells" were MANEUVERS in every manner but name and the fact that they still used the Ranger's crappy default spellcasting mechanics instead of the far better Tome of Battle mechanics.
So, while the SC made the Ranger's spellcasting "useful," the martial nature (no pun intended) of his new spells at the same time sort of heralded the end of the whole "divine connection to nature" part of the Ranger.
