Madlands

A Rakdos dual land that keys off the mechanic built to punish discard-as-a-cost, and the punchline is that cashing it in costs nothing. Madness with a value of zero means the reward for pitching this card is the card itself: discard it to a rummaging effect or a hand-size trim, and instead of watching it hit the yard you replay it for free, provided you still have a land drop that turn. Everything hinges on that provision. Because you can only play a land on your turn with a land play remaining, the card cannot cheat extra lands onto the battlefield the way a genuinely free permanent might; it converts a discard into a land drop rather than adding one. What it does do is make the discard costless, turning what is normally a resource you shed under duress into fixing you would have played anyway. It enters tapped and taps for black or red, which is the plainest part of the card and the part that matters least. The interesting piece is structural: the design is a gag on the very idea of a discard cost, a land whose penalty for being thrown away is that you simply pick it back up. Madness at zero is the cleanest possible statement that discarding this was never a downside.
