In the seventh and final season of Buffy the Vampire Slayer, the First Evil waged war on the slayer line, using its agents to kill-off as many potential slayers as it could, before that epic final battle (when Willow turned all the remaining potentials into slayers and they took on the army of Ubervamps in the Hellmouth).
What would happen if the First Evil existed in the MCU and targeted the Masters of the Mystic Arts in a bid to kill-off the Sorcerer Supreme line?
Let's say both prime Doctor Strange and the Ancient One exist simultaneously for this battle, while every other Master of the Mystic Arts (and those who might become one) exist as well.
The First Evil has all of its agents from Buffy the Vampire Slayer (Bringers, the original Ubervamp and the Ubervamp army, Caleb and other humans dotted around the world - such as the female prisoner who tried to kill Faith).
Who else would the First Evil recruit and add to its ranks in the MCU? How far would it get in its attempts to take down the Masters of the Mystic Arts?
Go!
