Pay no heed vs deathtouch

[DHartman]

Can you call deathtouch a source of my choice to play pay no heed on

[Steerpike]

{Pay No Heed}

[Steerpike]

You cannot call deathtouch the source, no. That is a quality of a creature, a creature being the source

[Wingnut]

Now, if the question is can you choose a creature that has deathtouch as the source, preventing that damage and negating the deathtouch, then the answer is yes.
