so its a magic april fool's joke? can someone explain what the joke is i dont understand sorry if its stupid question

[Arix]

It's not so much a joke as a tradition - every April Fool's Day, mtg.com just pulls something stupid like this (along with announcing a "new release" - in this case, Duet Decks).

I thought it was funny.

woudlve been funnier if they had released a spoiler of Dark Ritual with the New Phyrexia symbol, some people here wouldve even believed it...

but it would've made more sense for it to be printed in a core set.
