I like having a few cards in cube like this as well that during the draft process you need to decide, do you pick this, because you know that as long as your fixing is good enough this card will make the main deck and will improve the quality of your deck because running this > is better than a basic, or do you pick up that slightly better X drop etc but cut a card you already drafted.
yeah, this card is really cool. I think it needs some testing, the only thing I am afraid of, is casting this say on turn, if you don't have other ramp going on, you would only be able to add 1 counter that turns, and then on turn 5 you can lose a land, and pay 3 to destroy 2 mana cost permanents seems rather slow. on the other hand you can just cast is as a land, and when you run out of gas, you can use it as removal speel for most threats. Not to mention, it probably deserves a place just to help the land decks. Between this, strip mine, etc and crucible/loam, it looks like it can be a nice piece to give that deck a boost.
