Tajuru Preserver

As a spell or ability an opponent controls resolves, if it would force you to sacrifice a permanent (as the annihilator ability does), you just don’t. That part of the effect does nothing. If that spell or ability gives you the option to sacrifice a permanent (as Prowling Pangolin’s ability does), you can’t take that option.

You may still sacrifice permanents to pay the costs of spells you cast and abilities you activate, or because a resolving spell or ability you control instructs or allows you to do so. Notably, you may still sacrifice Eldrazi Spawn creature tokens for mana.

You may sacrifice a permanent as a special action, even if the effect that allows you to do so comes from an opponent’s permanent (such as Damping Engine or Volrath’s Curse). No one controls special actions.
