Text (10+errata): ~this~ enters the battlefield tapped. ; {Tap}: Add {W} to your mana pool. ; {1}{W}: ~this~ becomes a 1/5 white Soldier creature until end of turn. It's still a land. [Oracle 2009/07/08]
The animating ability sets the initial characteristics for the land creature. So, while you can use the ability again, it won't have any additional effect if used more than once. [Urza's Legacy FAQ 1999/02/03]
The land is subject to summoning sickness if you didn't control its card since the start of your most recent turn. [Urza's Legacy FAQ 1999/02/03] See Rule 302.6.
It has creature type "Soldier" since Tenth Edition and Oracle 2007/07/13. [D'Angelo 2007/07/15]
