Artifact, 1 (1) {X}, {T}: Untap X target lands.1 Tawnos learned quickly from Urza that utter simplicity often led to wondrous, yet subtle utility.
Illus. Douglas Shuler
This is not mana ability. It is a normal ability and it will resolve along with other spells and abilities in its stack. The lands untap during resolution. [D'Angelo 2000/02/25]
You may untap your opponent's lands if desired. [Aahz 1994/05/03] This can be useful if Power Surge is in play.
Can be used on an untapped land. [Duelist Magazine #5, Page 22]
