If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.

Mysterious Treasures is a set in the Diamond & Pearl series. It was released on August 1, 2007. The printed size is 123. This checklist is longer, at 124 cards. Magmortar is 12/123, in position 12 of 124 on this checklist. Before it is 11 Lumineon, and after it is 13 Meganium. The listed rarity is Rare Holo.
Magmortar is a Stage 1 Fire Pokémon with 100 HP. The card lists level 48. In the Pokédex this is Magmortar (#467), generation 4 (Sinnoh). The card says it evolves from Magmar. In this catalog that name is Magmar (#126).
Hiroaki Ito illustrated this card. The same name is on 3 other cards in the catalog.
Magmortar (#467) has 16 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Magmortar DP20/56 in DP Black Star Promos (2007). Both list 100 HP. The rarity there is Promo, and here it is Rare Holo. Daisuke Ito illustrated that card, and Hiroaki Ito illustrated this one. 14 other cards of Magmortar list a different HP.
The attack Smoke Bomb lists 30 damage. The cost is Fire, Colorless. If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing. Flame Drum is another attack lists 80 damage. The cost is Fire, Fire, Colorless. If Magby isn't anywhere under Magmortar, discard 2 Energy cards from your hand. (If you can't discard 2 Energy cards from your hand, this attack does nothing.) Weakness is Water +30. Retreat cost is 3. The flavor text reads "It blasts fireballs of over 3,600 degrees F from the ends of its arms. It lives in volcanic craters."
I keep a set binder for Mysterious Treasures, meant to hold every card of that set. This card is one slot in the Mysterious Treasures set binder. A generation binder holds one card of each species. Magmortar can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
