The “can’t regenerate” is an effect of Disintegrate and not an effect of the damage. It works even if the damage is prevented or redirected. If redirected, the damage does not take this effect with it.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
