Sorry for the vagueness but i'm at work and don't have the cards in front of me. Here's the situation: Matt has the white enchantment where you can tap 2 untapped creatures you control to tap target creature and has two untapped creatures. It is the start of my turn. I have the blue guy who lets you tap 2 untapped birds and him to return target permanant to its owners hand. During my untap step, he tries to tap my guy. In response, I tap him and 2 untapped birds I control to return the enchantment to his hand. He argues that I can't respond to his action and my guy stays perpetually tapped. I tell him he's wrong and he wants me to find out the answer on the net. SOo, who's right?
