text: Vengeful Archon’s ability doesn’t have you choose a source of damage. It will apply to the next X damage you would be dealt that turn, regardless of where that damage comes from. It doesn’t matter whether the damage would all be dealt at the same time. For example, if X is 4 and you’d be dealt 3 damage by Lightning Bolt, that 3 damage is prevented and Vengeful Archon deals 3 damage to the targeted player. The prevention effect will still apply to the next 1 damage you’d be dealt that turn.
