>>28959704How about adjusting already existing abilities?
1. Magician
Pokemon that have it: Fennekin line, Klefki, and both Hoopa forms
Description: User steals the target's item (with the exception of items that can't be moved like Mega Stones) and can keep it while it's in battle even when they already are carrying an item. So let's say your Magician already has leftovers, and they hit a pokemon that's holding a life orb. That pokemon will now hold both a leftovers and a life orb. Said pokemon also are immune to item affecting moves meaning that if a pokemon were to use Knock off on them, it will fail. Pokemon can carry up to two other stolen items, and once they reach this limit they can't steal anymore items until they use up any of the three items they have. Stealing effect will fail if used on a Pokemon that has Sticky Hold or Magician.
2. Pickpocket
Pokemon that have it: Sneasel line, Seedot line, and Binacle line.
Description: Similiar to the ability Magician, but instead of being immune to item affecting moves, they instead will inflict Taunt on the targeted pokemon as well when stealing from them.
3. Pressure
Pokemon that have it: Too many
Description: Makes enemy pokemon use up 3PP for 5PP moves, and a random chance between 3-4PP for any moves with 10PP or higher.
