Up for sale is the fragile Clay Pigeon, an uncommon card from the Unglued expansion of Magic: the Gathering. These are the original, silver-bordered, English version.
Clay Pigeon: 1/1 Artifact Creature with Flying; spend 1 mana and throw Clay Pigeon into the air at least two feet above your head while seated and attempt to catch it with one hand; if you catch Clay Pigeon, return Clay Pigeon to play, tapped, and the next time a source of your choice would deal damage to you this turn, prevent that damage; otherwise, sacrifice it; casting cost 3.
These cards are all in at least Very Fine condition, with most being in unplayed, Mint/Near Mint condition.
