Forbidden Light is a set in the Sun & Moon series. It was released on May 4, 2018. The printed size is 131. This checklist is longer, at 150 cards. Klefki is 89/131, in position 90 of 150 on this checklist. Before it is 88 Dedenne, and after it is 90 Xerneas-GX. The listed rarity is Uncommon.
Klefki is a Basic Fairy Pokémon with 70 HP. In the Pokédex this is Klefki (#707), generation 6 (Kalos).
otumami illustrated this card. The same name is on 44 other cards in the catalog.
Klefki (#707) has 10 other cards in the catalog. Those other cards are in 10 sets. The other printings with a release date run from 2014 to 2026. The earliest other card is Klefki 73/111 in Furious Fists (2014). That card lists 60 HP, and this one lists 70 HP. Both list the rarity Uncommon. 5ban Graphics illustrated that card, and otumami illustrated this one. 3 other cards of Klefki list a different HP.
The attack Metal Sound lists no damage number. The cost is Colorless. Your opponent's Active Pokémon is now Confused. Fairy Lock is another attack lists 20 damage. The cost is Colorless. The Defending Pokémon can't retreat during your opponent's next turn. Weakness is Metal ×2. Resistance is Darkness -20. Retreat cost is 1. The flavor text reads "It inserts its horn into chinks in metal, absorbing metal ions. For some reason, it collects keys."
I keep a set binder for Forbidden Light, meant to hold every card of that set. This card is one slot in the Forbidden Light set binder. A generation binder holds one card of each species. Klefki can fill a slot in Generation 6 binder (Kalos). I still need this card.
