Which commander made you do a double take when you first read it?

We’ve all heard about which commanders are overpowered and too good, entirely deck-defining, but a lot of these can sound innocuous if you’re not reading in deep. I know that the first time I read Etali I just thought “oh that’s nice you get free stuff of the top.” And thought it was a simply strong card. But then the other day I read chatterfang. And hoo boy, it has three effects:

Whenever you make any number of tokens, you get that many squirrel tokens too, enabling it to go infinite with a ham sandwich.

For one mana, it can kill any creature, in a way that gets around indestructible effects too.

And it randomly has forestwalk as a third tacked on effect on a 3 mana 3:3 body that only requires a single pip.

This card made me simply go “what the actual hell are they doing here. Why are there so many effects. Why does it double the tokens and not just give you an extra one. Why would it have kill on a stick.” And so many things. The only other card which I’ve had that reaction to is Vivi Oritnier where it grew larger, shocked the opponents, and could act as a massive mana dork. I was surprised it wasn’t restricted to instants or sorceries or anything.

So I’m asking you, which card or commander did you read and just get dumbfounded by. Just went “how the hell could they print this why does it do so much why does it do that.”
