Aquapolis is a set in the E-Card series. It was released on January 15, 2003. The printed size is 147. This checklist is longer, at 182 cards. Magneton is 22/147, in position 22 of 182 on this checklist. Before it is 21 Lanturn, and after it is 23 Muk. The listed rarity is Rare.
Magneton is a Stage 1 Metal Pokémon with 70 HP. 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.
Hikaru Koike illustrated this card. The same name is on 46 other cards in the catalog.
Magneton (#082) has 44 other cards in the catalog. Those other cards are in 34 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Magneton 9/102 in Base (1999). That card lists 60 HP, and this one lists 70 HP. The rarity there is Rare Holo, and here it is Rare. Keiji Kinebuchi illustrated that card, and Hikaru Koike illustrated this one. Retreat cost there is 1, and here it is 2. 34 other cards of Magneton list a different HP.
Magnetic Flow is listed as Poké-Power. Once during your turn (before your attack), if Magneton is your Active Pokémon, you may flip a coin. If heads, choose 2 of your opponent's Pokémon that have Energy cards attached to them. Choose 1 of the Energy cards attached to each of those Pokémon and switch them between the Pokémon. This power can't be used if Magneton is affected by a Special Condition. The attack Steel Wave lists 30 damage. The cost is Colorless, Colorless, Colorless. This attack does 10 damage to each of your opponent's Benched Pokémon that are the same type (color) as the Defending Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fire ×2. Resistance is Grass -30. Retreat cost is 2.
I keep a set binder for Aquapolis, meant to hold every card of that set. This card is one slot in the Aquapolis 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.
