(2/18/2022) If a creature in combat has first strike or double strike, you can activate the ninjutsu ability during the first-strike combat damage step
You have a few options for this effect
The various Swords, like Sword of Feast and Famine or Sword of Fire and Ice, are great choices, because while the creature gets the buff and the protections, you, as controller of the Sword, get the triggers, regardless of who controls Tahngarth
