This card does not target.
You cannot Chain “Pulling the Rug” to an Ignition Effect that was activated when a monster was Normal Summoned. (“Exiled Force”, etc.)
“Pulling the Rug” can be activated when any Trigger Effect is activated due to a Normal Summon. Even if the Trigger Effect came from a different monster than the one that was Normal Summoned. (In this case, the monster that produced the Trigger Effect is destroyed, not the monster that was Normal Summoned.)
