Flip a coin. If heads, the Defending Pokémon is now Paralyzed.

Base is a set in the Base series. It was released on 9 January 1999. The printed size is 102, and the checklist is the same length. Magneton is 9/102, in position 9 of 102 on this checklist. Before it is 8 Machamp, and after it is 10 Mewtwo. The listed rarity is Rare Holo.
Magneton is a Stage 1 Lightning Pokémon with 60 HP. The card lists level 28. In the Pokédex this is Magneton (#082), generation 1 (Kanto). The card says it evolves from Magnemite. In this catalog that name is Magnemite (#081). The card lists Magnezone, Magnezone (#462) under evolves to.
Keiji Kinebuchi illustrated this card. The same name is on 212 other cards in the catalog.
Magneton (#082) has 44 other cards in the catalog. Those other cards are in 33 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Magneton 11/62 in Fossil (1999). That card lists 80 HP, and this one lists 60 HP. Both list the rarity Rare Holo. Ken Sugimori illustrated that card, and Keiji Kinebuchi illustrated this one. Retreat cost there is 2, and here it is 1. 41 other cards of Magneton list a different HP.
The attack Thunder Wave lists 30 damage. The cost is Lightning, Lightning, Colorless. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Selfdestruct is another attack lists 80 damage. The cost is Lightning, Lightning, Colorless, Colorless. Does 20 damage to each Pokémon on each player's Bench. (Don't apply Weakness and Resistance for Benched Pokémon.) Magneton does 80 damage to itself. Weakness is Fighting ×2. Retreat cost is 1. The flavor text reads "Formed by several Magnemites linked together. It frequently appears when sunspots flare up."
I keep a set binder for Base, meant to hold every card of that set. This card is one slot in the Base set binder. A generation binder holds one card of each species. Magneton can fill a slot in Generation 1 binder (Kanto). I still need this card.
