As he jumps out of the way of Lambert's sign, Strange slips the creepy wife gem back into his pocket. The bicorn starts to flail and one hoof shoots directly towards Strange's head. Without hesitation, he scrunches up his eyes and poofs into smoke, as the hoof passes harmlessly through where his head used to be. He floats back a foot or so and reforms into his normal self, kneeling on the ground.

Obviously Strange can't do much magic inside the magic-blocking circle. But he can at least do some things around it. Placing one hand on the ground, Strange quickly mutters an incantation. A few pillars of earth start to shoot up around the magic circle, trying to block the bicorn and keep it from jumping out of the circle.
