Dread Presence
Creature — Nightmare
Whenever a Swamp you control enters, choose one —
• You draw a card and you lose 1 life.
• This creature deals 2 damage to any target and you gain 2 life.
It beckons silently, waiting in the darkness.

A Swamp is a land with the subtype Swamp, not any land with a mana ability that produces black mana.

If you choose the second mode and the chosen target is an illegal target by the time Dread Presence's triggered ability tries to resolve, the ability doesn't resolve. You won't gain 2 life, and the ability won't change to the first mode.
