For what its worth, I also add that we all desire this.

I wouldn't go that far.

3-4 turn CD so I'm not stuck casting dead spells at the end of my turn against opponents with superior momentum economy and regular Steal, pretty please.

I will say as a note it does make the Diary Lock weapon part a lot more useful, I think that this suggestion is fine personally if Spell Snatch comes with say a 2 round CD, so there are times where equally the spell snatcher has windows where they can't steal spells very reliably, this also makes it so you can mask important spells behind another spell usage, say using Mass > Rescue > Graft is risky, but not Mass > Graft > Brighten as I doubt you'll miss the Brighten.

It is within the lore to say that the spells eventually come back, equally I would not be opposed to recalling the spell again after say 5 rounds (in which case no CD may be needed)
