Dread has the following ability:
Whenever a creature deals damage to you, destroy it.
If we are playing a Two-Headed Giant game and one player puts a Dread onto the battlefield, can I attack the other person in the team to avoid losing my creatures? (I know with certain effects like Crosis, the Purger I can choose who I attack to make them discard a card, but I'm not sure on how Dread would work.)
