Whenever Sensational Spider-Man attacks, tap target creature defending player controls and put a stun counter (If a permanent with a stun counter would become untapped, remove one from it instead.) on it. Then you may remove up to three stun counter (If a permanent with a stun counter would become untapped, remove one from it instead.)s from among all permanents. Draw cards equal to the number of stun counters (If a permanent with a stun counter would become untapped, remove one from it instead.) removed this way.
