Opponent played a Suspicious Alchemist, triggering my Kidnap secret.
They then killed the 0/4 Sack on the same turn, returning the Suspicious Alchemist to their hand, but they did not play it again.
On my turn, I got to guess from the same set of spells twice.
I incorrectly guessed the card at first, but got it correct on the second try as it was already revealed to me.
