What are very unique and unusual commanders?

For me, I have the most fun brewing decks for weird commanders. Here are a few of the weird commanders that I made decks for:

[[The Most Dangerous Gamer]] this deck routinely cheats out 10+ attractions a game and is always a fun time. My pet deck that is so much fun. Every card is legal to use: Moxfield

[[Magar of the Magic Strings]] turn sorceries into creatures. Moxfield

[[Greven, Predator Captain]] 1 shot people out of nowhere, uses life as a trading resource. Moxfield

[[Marvo, Deep Operative]] top deck + clash to chest out big spells. Uses all the old clash cards. Moxfield

What are some unique decks you like? I’m specifically talking about weird interactions you can only have with your commander. Another example I was thinking was [[Brigid, Hero of Kinsbaile]] and do a bunch of deathtouch/lifelink/tap/untapping shenanigans.
