Worst trades you've made

[Dudecore]

I've traded a number of things over the years for almost nothing. I traded {Mox Opal}s for next to nothing, because I didn't (and still don't really) think it was a great card and that it would be playable.

I've mostly been savvy though, I can't really think of anything that I've completely been beaten up with losing.

I traded  {Akroma, Angel of Wrath} foil for some yugioh cards several years back.

The night of the gate crash pre-release I traded a  {Boros Reckoner} and a  {Boros Charm} for a  {Watery Grave}. I goofed 😲😲😲

I can't find my {Chain Lightning}s from the Fire & Lightning Premium Decks. Really sad now, must have traded them when I was a noob.

[Crapshooter]

Traded a  {Jace, the Mind Sculptor} for  {Emrakul, the Aeons Torn} when it first came out. Even trade then, still have the emrakul and now a play set of jaces. Bad trade, but I'm not hurt too much over it.
