To you, what does "a little more money" look like? Right now, the deck is 15$.
I think my biggest suggestion for you is also a question. What is your goal with this deck? Right now, it seems like general aggro with maybe some graveyard interaction? Find a card or mechanic that really excites you in this deck, and focus the deck around it. That will make it easier to pick out other cards to put in the deck while also increasing its power.
From your post it sounds like you've been playing for a while, so I have two more suggestions. One, try to move toward having 4x copies of each card you're including. It's okay to have fewer, but there should be a reason to have fewer other than "versatility". Without tutors, versatility is really just more randomness. Two, think about how fast you want this deck to play and adjust the mana curve accordingly. Right now you've got creatures at 3 - 8 - 3 - 1 - 4 - 2; If you're curving out at 6 CMC, then maybe something like 6 - 6 - 8 - 6 - 4 - 4 will help you to more consistently have plays throughout the game.
