1997 world champion mtg card Ebony Charm (Jakub Slemr) (SB) [World Championship Decks 1997] Magic: The Gathering 1997 World

Madness has cropped up in multiple sets, including several Innistrad-based sets as a vampire typal mechanic, so you can go either way

You can just get single cards instead, and Ive rounded up the best of them for you in this article

This three mana sorcery has two modes, one of which adds one red mana for each card in an opponents hand, while the other lets you exile the top three cards of your deck and play them this turn

What I really love about this card is that it offers brewers the ability to think wayyyy outside the box, reaching for a world where they can get a bunch of artifacts into play more easily than other ramp options, with an end game that involves casting either a) a non-artifact spell that wouldnt normally be easy to ramp into and benefits from board state full of tapped artifacts or b) a cost reduction ability like the one on Etherium Sculptor that lets you chain a bunch of spells in a flurry for purposes yet unknown
