Concentration brisée

Cards are discarded in a Magic game only from a player’s hand. Effects that put cards from a player’s library into that player’s graveyard do not cause those cards to be discarded.

Casting a spell for its madness cost doesn’t change its mana cost or its converted mana cost. You just pay the madness cost instead.

If you choose not to cast a card with madness when the madness triggered ability resolves, it’s put into your graveyard. You don’t get another chance to cast it later.

If you discard a card with madness while resolving a spell or ability, it moves immediately to exile. Continue resolving that spell or ability—the card is not in your graveyard at this time. Its madness trigger will be placed onto the stack once that spell or ability has completely resolved.

Madness works independently of why you’re discarding the card. You could discard it to pay a cost, because a spell or ability tells you to, or even because you have too many cards in your hand at the end of your turn. You can’t discard a card with madness just because you want to, though.
