This effect prevents a card from being affected by effects. For example, your Digimon won't suspend if it's chosen for a "suspend 1 of your opponent's Digimon" effect, and its DP won't be reduced by 3000 if it's chosen for a "1 of your opponent's Digimon gets -3000 DP" effect.

It will be affected by the gained effect as soon as it can be affected by effects.

If the Digimon isn't affected by effects upon the trigger timing, the effect won't trigger.
