D&D 5E Need help with a character

[Nitemere]

I am new here. But I been looking for some help to make a broken character for a 1 off. This person that is DMing always makes characters that are broken and OP.
I have to come up with by the end of the day.
I haven't played D&D since 3.5. After reading up on classes and stuff I really like the Artificer class. This is what I came up with

D&D Beyond Character Sheet

The World's most intelligent Dungeons and Dragons Character Sheet.

But if someone knows a really broken character they can build for me would be awesome. I kind of want to get him a taste of his own medicine.
All other classes in this campaign are rogues, bards, and druids

Again thanks for the future help.

Depends on your party and level

But Owlin Rogue with a bow can out run nearly anyone.

Start fighter 1 for archery style and longbow proficiency.
Then Rogue 2 for Cunning Action.
Scout Rogue just in case anyone gets close.
Pick up Sharpshooter at Rogue 4 for more range.
Go Shadow Monk 6 for extra speed, the Mobile feat, multiple attacks, and teleport.

You might end up leaving the rest of your party for dead, but you'll be nearly impossible to catch.
