Up for sale is the sneaky Baloth Cage Trap, an uncommon card from the Zendikar expansion of Magic: the Gathering. This is the original, black-bordered, English version.
Baloth Cage Trap: Instant; if an opponent had an Artifact enter the Battlefield under his/her control this turn, you may pay 1G rather than pay Baloth Cage Trap's mana cost; put a 4/4 Green Beast Creature token onto the Battlefield; casting cost 3GG.
These cards are all in at least Very Fine condition, with most being in unplayed, Mint/Near Mint condition.
