I've been searching far and low on the sub to understand it. I can't seem to figure out how this fully works and when its supposed to proc. I'll use Ice and Pyre as an example card because thats all I remember from the top of my head about what has Attuned right now.

I tried playing Ice and Pyre to see if the Attuned effect goes, but it didn't seem to. I tried to maybe keep it in hand to see if it would spread the effect to my other spells, didn't do that. Unfortunately, I have yet to come across an Attuned card on the last 3 turns of a game, so I can't confirm if thats when Attuned procs.

I hate asking such a stupid question, but so far I haven't found a way for this effect to work and its been driving me crazy a bit. Thanks in advance!
