If you or your players are new to the amnesiac, there is nothing wrong with just riffing on an already existing character (example: each night, pick a player, you learn if one of their alive neighbours is a Demon - basically an empath/fortune teller/seamstress knock off).
The best abilities give the amnesic some sort of feedback that they can use to solve their ability; having the amne picking players each night and learning nothing can be frustrating for them, even if you know they're helping the good team win.
If your ability is so long it wouldn't fit on a token, you need to simplify it.
If your ability hard confirms an amnesiac in play, that's probably not going to work either, remember that evil should be able to bluff amnesiac if they want to. That doesn't mean you can't get a little wild - one of my favourite abilities I've run was "each night, pick a player, another amnesiac learns their character. If you die, the other amnesiac dies [+1 amnesiac]" in a game with the potential for multiple deaths.
