- Psychokinesis targets 1 card on the field.
- Destroying the targeted card and inflicting 1000 damage are considered to happen at the same time.
- If an effect is chained that removes every Psychic-Type monster from your side of the field, the effect of Psychokinesis still resolves.
- If an effect is chained that removes the targeted card from the field, the damage is not inflicted.
