[HELP REQUEST] Fiend Deck w/ old cards needs improvement, low budget

[hell_sword2280]

Here's a link to an old thread I posted since my deck is essentially the same:

 

My Fiend Deck

 

I realized later that its one card short :/ oopsie.

 

Please, I'd really like this deck to work it's got a lot of my best cards.

 

Peace,
