Mine is definitely Hua Tuo, Honored Physician. I love decks with consistent value engines, and he’s an interesting commander with less than 150 decks on scryfall.

Note: I tend to build budget decks because I am a poor student with a lot of debt, though the only expensive upgrades I can think of would be cards like Apex Devastator .
Sideboard is filled with cards that I haven previously had in the deck. Felt that pipers like howlpack piper and Champion of Rhonas are clunky because I generally want to be casting creatures from the top of my deck, not from my hand.
Lynde, cheerful tormentor is an awesome take on an agressive/malicious enchantment deck. Though it can be grindy, it has solid win cons in curse of unbinding, curse of thirst, curse of fools wisdom + wheel combos, and pucas mischief control lines. Plus you get to play some unconventional card draw/tutors like curse of misfortunes or curse of surveillance
