Budget Atraxa help?

I’ve always wanted to play atraxa toxic build and I absolutely know the friendships I’m ending. But I don’t have $800 to spend on a deck and my pod usually plus in 3 mostly anyways. So I’m ok with slowing the deck down.

Can you recommend cheaper/better cards for me to replace or am I where I should be? Do I have enough of everything?
