U.A. Mighty Slugger

The effect "You can Special Summon this card (from your hand) by returning 1 'U.A.' monster you control, except 'U.A. Mighty Slugger', to the hand" is not classified as an Ignition Effect, Trigger Effect, Quick Effect, or Continuous Effect. (No Chain Link is created when performing this Special Summon.)

When performing a Special Summon using the effect "You can Special Summon this card (from your hand) by returning 1 'U.A.' monster you control, except 'U.A. Mighty Slugger', to the hand," the procedure is to return 1 face-up "U.A." monster you control to its owner's hand, and then Special Summon this card. (The process is not considered complete upon returning the monster to the hand.)

The effect "②: If this card attacks, your opponent cannot activate cards or effects until the end of the Damage Step" is a Continuous Effect.

If "U.A. Mighty Slugger" itself attacks, the effect "your opponent cannot activate cards or effects until the end of the Damage Step" is applied whether it attacks your opponent directly or attacks an opponent's monster.
