Dark Fiend Deck Feedback Plz!

Can someone plz give me feedback on how to improve my deck. I want to maintain it a dark fiend deck so any suggestions towards those lines would be greatly appreciated.

Thnx Adriana! ^.^

Adriana is a bot, she doesn't mean what she says :/

On Topic: For starters, you should replace the bad s/t's for cards that are much more useful. For example, take out the lightning vortex for dark hole, does the job without having to discard.

As for traps, take out the magic cylinder's for bottomless trap holes or d prisons, also, take out the back horn of heaven and whatever the 2 cards at the bottom right are for solemn warning and judgement, that will also leave your deck at 42 cards.

Other than that, I don't really know what your deck is other than being a random mash of some good but mostly meh cards
