If Deadpool's ranged attack card has its effect cancelled, or he moves out of range, does the attack end?

Question

Accepted Answer

No. A cancelled effect leaves the card blank, but the attack continues. Range is checked only when the attack is declared, so moving out of range does not end it, and combat damage still applies.
