Recognizing her great power, Lord Voldemort has convinced Wanda to fight on the side of the Death Eaters at the battle of Hogwarts, promising her the power Dumbledore may have hidden somewhere within (the resurrection stone) could be used to revive her lost love (Vision). Desperate and distraught, she agrees and is determined to fight on the side of the Death Eaters.
How would the Hogwarts defenders fare were they to come under attack by the Scarlet Witch?
Wanda is emotionally invested in winning this fight, starting positions are as in Deathly Hallows (Wanda starts across the bridge from Hogwarts on the hill overlooking it, with the Death Eater army). Hogwarts has prepped as they did in that novel/film. HP characters are composite. For rounds including Voldemort, he still has the Horcruxes he does as of the start of that battle, in the locations they are at that time. All HP characters (Hogwarts and DE) have the same motives and intentions as in canon, though Voldemort would be happy with Scarlet Witch killing anyone EXCEPT Harry (who he wants alive, if incapacitated, so he can finish him personally). Can Hogwarts withstand the power of the Scarlet Witch?
Rounds are as follows:
R1: Endgame Wanda attacks with Death Eater army
R2: Dumbledore is alive and among the defenders
R3: Peak-Wandavision Scarlet Witch is sent to attack alone
R4: rounds 2&3 combined
R5: R3, but Voldemort and Bellatrix back her up
R6: R4, but Voldemort and Bellatrix back her up
Bonus: All out... Death Eater Army + Peak Scarlet Witch VS Hogwarts Army (with all reinforcements) + Dumbledore
