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

Magmortar is Pokédex #467, generation 4 (Sinnoh). Magmortar is a Stage 1 Fire Pokémon with 100 HP. The card lists level 48. The card says it evolves from Magmar. In this catalog that name is Magmar (#126).
Magmortar sits at DP20/56 in DP Black Star Promos, position 20 of 56. Before it is DP19 Darkrai LV.X, and after it is DP21 Raichu. The set belongs to the Diamond & Pearl series. It was released on May 1, 2007. The printed size is 56, and the checklist is the same length. The listed rarity is Promo.
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."
Magmortar (#467) has 16 other cards in the catalog. Those other cards are in 15 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Magmortar 12/123 in Mysterious Treasures (2007). Both list 100 HP. The rarity there is Rare Holo, and here it is Promo. Hiroaki Ito illustrated that card, and Daisuke Ito illustrated this one. 14 other cards of Magmortar list a different HP.
The illustrator line reads Daisuke Ito. I count 47 other cards in the catalog with that illustrator.
DP Black Star Promos set binder is where a full DP Black Star Promos set goes. This card fills one slot there. A generation binder holds one card of each species. Magmortar can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
