Plus if you're the one "controlling" Nature by playing the cards, shouldn't you be able to wield it effectively?
I wouldn't think so, no. For a force this destructive, I wouldn't expect the one who invokes to be immune. This is far from being the first case of a suicide attack, or double-edged sword if you prefer, in games such as this.
The problem as I see it is that you're only looking at this card from the perspective of someone who's playing a Nature or Destruction deck. As dindon pointed out, there are other cards that don't mesh with what would seem to be the best strategy for using the majority of cards with a given keyword, but if they all acted toward the same goal, all cards of a given keyword would be the same. We have Unliving cards that reduce the opponent's tower. We have Soldiers that increase your tower or wall. We have Alliance that don't increase resource gain. They might not be what you expected to draw, but they might turn out to be what you need, and they make the game fun and strategic rather than a series of dice rolls.
This is one of those cards that you include in decks not focusing on the keyword, and it works very well with other strategies. Occasionally, it might by summoned by its keyword, and it could be useless, or it could be that you were playing an opponent with an Alliance deck who's just about to gain a resource victory...
