Our Influence Grows

When you set this scheme in motion, tap up to
two target lands for each opponent, target land does not untap during its controller's next untap step. For every two lands tapped this way, search your library for a basic land card, put it onto the battlefield tapped, then shuffle your library.
"Wars are not won on the battlefield alone, my son,
but in the hearts and souls of our adversaries."
- Emperor Yoshiro speaking to Prince Tatsu
