I brewed a Stangg EDH deck using only cards I found in my unorganized Magic drawer. Did I cook?

I decided to scan my drawer full of cards that I have been neglecting for years. After evaluating it all, I figured I could make a pretty decent Stangg deck. It's nothing weird or special, but let me know if you guys think it'll be alright for a couple games at the LGS. Any super cheap swaps I can make?
