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.
I think Ulasht, the Hate Seed is the Commander I’ve used with the least decks. He’s like a Gruul Ghave, which gives you access to things like mana echoes and impact tremors, the fact that he can ping things also causes fun combos with cards like Scythe of the Wretched
