Casting it and immediately exiling a threat is strong, and you can follow that up with more mana or cards and life
In fact, one could build an entire deck based around this card and sacrifice synergies related to Treefolk
For instance, a deck built around morph, which involves playing lots of creatures that cost three mana, will likely play more 1mv ramp spells, just like a deck with a commander that costs three mana
These can be incorporated into your decks as a subtheme sometimes, or they can occasionally be a main theme in a very particular/lucky draft
And thats just the Commander Decks, the full release runs deep
Id probably build this as a sacrifice deck to more consistently activate this commanders abilities
