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

DP Black Star Promos is a set in the Diamond & Pearl series. It was released on May 1, 2007. The printed size is 56, and the checklist is the same length. Magnezone is DP32/56, in position 32 of 56 on this checklist. Before it is DP31 Heatran LV.X, and after it is DP33 Dusknoir. The listed rarity is Promo.
Magnezone is a Stage 2 Metal Pokémon with 130 HP. The card lists level 51. In the Pokédex this is Magnezone (#462), generation 4 (Sinnoh). The card says it evolves from Magneton. In this catalog that name is Magneton (#082).
Kent Kanetsuna illustrated this card. The same name is on 74 other cards in the catalog.
Magnezone (#462) has 27 other cards in the catalog. Those other cards are in 20 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Magnezone 8/130 in Diamond & Pearl (2007). That card lists 120 HP, and this one lists 130 HP. The rarity there is Rare Holo, and here it is Promo. Nakaoka illustrated that card, and Kent Kanetsuna illustrated this one. Retreat cost there is 4, and here it is 2. 26 other cards of Magnezone list a different HP.
The attack Mirror Shot lists 40 damage. The cost is Metal, 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. Magnet Slash is another attack lists 100 damage. The cost is Lightning, Metal, Colorless, Colorless. Discard all Lightning Energy attached to Magnezone. Weakness is Fire +30. Resistance is Psychic -20. Retreat cost is 2. The flavor text reads "It evolved from exposure to a special magnetic field. Three units generate magnetism."
I keep a set binder for DP Black Star Promos, meant to hold every card of that set. This card is one slot in the DP Black Star Promos set binder. A generation binder holds one card of each species. Magnezone can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
