Jewel of Nzoth actually probably ruins this deck, if your board is full of rat kings its going to be hard to revive them as you wont have space to spam tokens

Animated Broomstick has such incredibly high potential to lose you the game due to you pulling it from Strength in Numbers that I dont think its worth running

Seems fun, but important to note Kelthuzad activates after the spell does, so you need to be careful if using him with a board clear
