Random Generator gave me Beseech the Queen and Ravaging Riftwurm. I was very afraid this card was going to get very texty. Unfortunately, the only thing it steals from Beseach is the cost and a love for finding out what that cost was, but it will do.

Would it be simpler as "Vanishing. ~ enters the battlefield with a time counter on it for each land you control"? Otherwise I suspect there may be some confusion (If I have , I can still not get the better version? Often 6 and get similar creatures :)).

You know, that's an interesting suggestion, and I know this is a sideways look at getting a large creature. As it stands, Green mana doesn't make this creature better, it just makes it cheaper, which was kind of my point. I also like the idea that, to get the most bang for your buck, you've really got to play with the mana you're using to put this thing into play. Unfortunately, while I think that's cool, I think you're right that player expectation will say "Hey, I'm paying a lot of Green here! I should be getting a bonus for that!"

Let's see if anyone else has an opinion on this thing. I'd be more than happy to more it to your method, but I'm not sure who cares more about this sort of creature, Johnny or Timmy.

Jack's first suggestion is very similar to Tidewalker, although there's something to be said for making a green version of that.

But this card as it is definitely makes me tap my lip (to invoke JMS, who helped define the archetypical Johnny).

I know, its funny. I personally like my version better, but I like Jack's idea for what it is. While mine makes an interesting one shot, I think Jack is on to a whole cycle of cards that have costs that do more if you pay more . Cool idea, and probably one that Wizards hasn't thought of yet.
