When Kaho, Minamo Historian enters the battlefield, search your library for up to three instant cards, exile them, then shuffle.
{X}, {T}: You may cast a spell with mana value X from among cards exiled with Kaho without paying its mana cost.
If an effect takes a card Kaho exiled out of the Exile zone, then you can’t use Kaho’s ability to cast that card.
If another player gains control of Kaho, that player may cast any of the cards exiled with Kaho’s ability.
Kaho’s activated ability refers only to cards exiled by its triggered ability. If another effect exiled the cards, you won’t be able to use Kaho to cast those cards.
