Ehh I am kinda new to making decks, haven't played in awhile but here is my deck.

What is the deck's aim?

Mainly balance, also try to get enough monsters out and not actually have to do most of damage with attacks themselves. I have no idea what I'm talking about lol

So basically, beatdown?

Mhm

Ok, first thing I noticed was that many of your cards had low attack. Using those ninja cards isn't a wise choice as many of them are situational, particularly that level 5 one with the ability to be special summoned (and it remained with low attack) - try replacing such cards with ones like Cyber Dragon.

Also add some Dark Bribes, Solemn Judgements, Solemn Warnings, maybe even some Swords of Revealing Light, depending if you want a secondary theme to your deck (such as lockdown beatdown or something lol)

Next, remove the field spells and add in cards such as Gold Sarcophagus, Mystical Space Typhoon and anything else you can find that would fit in such a theme. The idea of a deck is for it to be able to do one thing quickly and effectively. This can't be done if you have lots of situational cards or cards that are weak on their own or even together.
