Other than hexproof creatures, he's possibly my favorite body for GW or Bant hexproof decks in casual. Honestly, probably even more than hexproof, just because I like my casual magic interactive.

Take your favorite Aura (Unflinching Courage, anyone?) and add cheap regeneration and first strike. Turn three Ranger, turn four Courage with regen mana up for a regenerating 4/4 with trample, lifelink, and first strike. And that's assuming your green deck somehow has no acceleration.
