×2Mischievous Lock
As long as this Pokémon is in the Active Spot, Basic Pokémon in play (both yours and your opponent's) have no Abilities, except for Mischievous Lock.
JoustBefore doing damage, discard all Pokémon Tools from your opponent's Active Pokémon.
In the past, noble families entrusted their vault keys to a Klefki. They passed the Klefki down through the generations, taking good care of it.
Can you use Iron Leaves ex's "Rapid Vernier" Ability while Klefki's "Mischievous Lock" Ability is active?
No, you cannot. Rapid Vernier does not activate until Iron Leaves ex is on the Bench, at which time it is considered "in play" and therefore blocked by Mischievous Lock.
If I have Klefki with "Mischievous Lock" Ability active and switch or retreat it to an Iron Valiant ex with "Tachyon Bits" Ability, can I use Tachyon Bits?
Yes, when Iron Valiant ex switches in Klefki is no longer there, so Mischievous Lock does not prevent the use of Tachyon Bits.
What happens if Klefki with "Mischievous Lock" and Empoleon V with "Emperor's Eyes" Ability somehow both become active at the same time, like at the start of the game?
If Abilities activate at the same time, the Abilities of the player whose turn it is activate first.
If Empoleon V with "Emperor's Eyes" Ability is in the Active Spot and my opponent brings up a Klefki with "Mischievous Lock" into their Active Spot, whose abilities are turned off?
Since Emperor's Eyes was in effect before Klefki became active, it takes precedence and Mischievous Lock does not activate as long as Emperor's Eyes is in effect. The converse is also true, if Klefki were active first and Empoleon V is brought up, Emperor's Eyes would not activate.
If I use Klefki's "Joust" attack against a Pokemon with Handheld Fan attached, does the Handheld Fan get discarded before it can move an Energy from the Attacking Pokemon or not?
Since the Handheld Fan gets discarded before damage is done, it cannot move an Energy from the Attacking Pokemon to one of the opponent's Benched Pokemon.
