When each battle phase starts, if you have at least 1 unit with Cunning or Stealth in any arena, choose one: Draw a card. Or: Your opponent loses 1 Force.
Keywords
Stealth
Stealth: An isolated, static ability that means, "This unit can't be attacked unless it's tapped or has damage counters on it." An untapped and undamaged unit with Stealth can still be affected by alternative types of damage. (Such as Overkill.) As long as the unit has any number of damage counters on it, it can't use Stealth.
Cunning
Cunning: An isolated, static ability that means, "Roll this unit’s attack dice secretly. Show them to your opponent after damage prevention."
