The next turn was the same thing, the second copy of Devil Chains getting the flashback of Abyssal Vows, and he called out that she skipped her draw step as he searched for a third. A second chain and shackle shot out of nowhere, grabbing her other leg, and both pulled lightly, making her legs go spread. She was halfway locked down.
His next turn was almost as mean. “I play Eldrazi Monument. As long as I sacrifice a creature each turn, my creatures have flying, indestructible, first strike, and +1/+1. Then I play Awakening zone, giving me a 0/1 every turn. Third Devil Chains attacks, you cannot play non-creature spells now.” He searched for the fourth, putting it out almost triumphantly. A third chain shot out, grabbing her cardless hand, and pulling it up and to the side.
The fourth one soon attacked as well, and a chain grabbed her last hand, pulling it as well, so she was spread eagle in the chair. “Seems you’re completely locked down now.”
