Keywords
Deflect
Deflect X: A layered ability activated during the damage prevention POP that means, "Prevent X damage to this unit, and this unit may do that much damage to a unit of your choice in the same arena." Deflect creates new damage that can be done to any unit in the arena (even itself). Deflect may be deflected any number of times. Damage is applied after all prevention and deflects resolve. The damage that the unit does equals the damage it prevented. You can play each Deflect effect only once for each source of damage. Deflect as much damage as you can up to the Deflect value.
Equip
Equip: A selective effect on Equipment activated during the build step that means, "Attach this Equipment to a unit. Play only during your build step." You can pay the Equip cost only once per turn.
Shields
Shields X: A cumulative, static ability that means, "The attacking unit gets –X power against this unit." Shields only matters when attack dice are rolled. If you give a unit Shields after your opponent has rolled for damage, it doesn't affect the roll.
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.
