help building shorikai - cutting cards (my first brew)

Hi everyone! https://archidekt.com/decks/12042107/azorius_shorikai_budget_control_50_euro_budget

This is my first brew and I've decided to try my hand at a control vehicle/artifact shorikai deck, and my deckbuilding process was absolutely wrong: i just added cards that I thought were needed for the deck. Currently, it is pretty synergestic, but there is an issue

The deck is 100 cards; i'm trying to cut cards but it's really hard to pick what to cut and what not to cut while maintaining a degree of balance within the deck.

Any advice on what to cut or how to cut would be greatly appreciated. Thankss
