Make me an Inventory Tracking Google Sheet (Code Provided)

Job ID: 39397782

Budget: $14 – $30 NZD

I have the code for this already. I just need someone to make it work perfectly and look as sleek as possible.

This is a very easy task for the right person. I am seeking an under the sea vibe.. think Atlantis meets SpongeBob. Dark tones, pixel-y mascot (I have all of this already), I Just need the UI to be as clean as possible.
The sheet will scrape data from Scryfall.com and present both a USD and NZD price. If possible I would like the sheet to update in real-time, if not the code provided should allow a button to be pressed.

I need this implemented:

Cards to be in Color Coded Sheets
Cards to be shown in Price (highest first) order
A template that is modern, clean, or goes further into the deep-sea theme.

All code is provided and this should not take long.

Thank you
