Card Rulings

10/1/2007 Wren’s Run Packmaster gives deathtouch to all Wolf permanents you control, not just the tokens it creates.
10/1/2009 A Wolf’s deathtouch ability will apply if both Wren’s Run Packmaster and that Wolf are on the battlefield at the time the Wolf deals damage. The creature dealt damage by the Wolf will be destroyed the next time state-based actions are checked, even if the Wolf or Wren’s Run Packmaster leaves the battlefield.
