Text (MR+errata): {Tap}: Add {1} to your mana pool. ; {6}: ~this~ becomes a 3/3 Elemental artifact creature that's still a land. (This effect lasts indefinitely.) [Oracle 2009/07/08]
The land is subject to summoning sickness if you didn't control its card since the start of your most recent turn. [D'Angelo 2002/06/18] See Rule 302.6.
Note - This card did not have a creature type when animated until Oracle 2007/10/01, when it became "Elemental".
