Permanent land conversion wouldn't be appropriate for common though - and considering the importance of land types in this set would be highly complex.
In the current version "as long as ~ is on the battlefield" is redundant text.
Are you certain you want the land conversion to be a static ability? As much as the original version was a bit underwhelming, this new version is overflowing with complexity and book keeping concerns - leaving unused/meaningless mire counters floating around the battlefield etc.
Cute
Separate targets. Might be cleaner to give the goblin tokens an ETB effect that does the same thing?
Back to the original...
