Brainiac:
Action: Until the end of the phase, increase or decrease a number on target non-objective card in play by 1 (limit once per turn)
Clearing house:
Reaction: After an opponent resolves a card effect that draws 1 or more cards, remove a focus token from this enhancement
So I use brainiacs ability to change the "draws number to 0 or more" meaning that any opponents card effect, whether it be a fate card, event, triggered ability, would remove a token from the clearing house. Is this correct?
