Game Preserve

Free creatures from the top of the library, but only if the entire table cooperates. The trigger checks every player's revealed card at once, and a single land, instant, or sorcery anywhere breaks the deal for everyone. That makes it the rare green ramp engine you cannot steer: you can stack your own deck toward creatures with library manipulation, yet you have no control over what the player across the table flips, and their stray noncreature card costs you your own payout. The math only gets worse as the table grows, since more libraries means more chances that one reveal isn't a creature, and the trigger fizzles into nothing more often than it fires. It belongs to an older strain of green design, the kind built around symmetrical engines that hand the same gift to every opponent whose library happens to line up. Where green usually cheats bodies into play through sacrifice, discard, or a private tutor, this one answers the same impulse with a communal lottery: it accelerates creatures onto the battlefield, just not necessarily yours, and never on your terms. The interesting part isn't the upside; it's that you're the one who started the coin flip, and the coin belongs to the whole table.
