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.
