Goblin Marauding Squad

The effect "When this card declares an attack, your opponent cannot activate Spell/Trap/Monster effects" is a Continuous Effect.

The effect of "Goblin Attack Force" that prevents the opponent from activating Spell/Trap/Monster effects only applies at the time of the attack declaration. During the Battle Step or Damage Step after the attack has been declared, the opponent can activate Spell/Trap/Monster effects as normal.

When "Goblin Attack Force" declares an attack, the opponent cannot activate the effects of Spell/Trap cards, such as "Ultimate Offering".

The effect "If this card attacks, it is changed to Defense Position at the end of the Battle Phase, and its battle position cannot be changed until the end of your next turn" is a Continuous Effect.
