Lands having hexproof is shockingly relevant across many formats. I wonder if this ends up seeing more play than people expect? It pretty much shuts down almost any kind of LD strategy, turns off Strip Mine, Rishadan Port, Field of Ruin (and friends), and so on. The activated ability is also something you can use with fetchlands if you have the spare mana and need to surveil. Plus, the 3/2 body could end up being pretty aggressive.
