Thanks Spiff for the quick clarification.
Bunker with Ammo Drop destroying Tome of the Unknowable. Both of those cards have conditional triggers of a card being destroyed. These are now simultanious triggers, which means that the order of resolution will depend of what card was out first.
If this was Advanced mode, Tome would act first since it must have been in play before Ammo Drop. Its trigger resolves first, searching for Condemnatiom, then will move to the trash since it now has completed its final effect. Bunker now draws his card safely.
If it was the other way around, Bunker would draw his Ammo Drop card first, triggering Tome to play the top card of the deck (and newest consecutive triggers always go first). Fallen Angel would NOT heal the Tome, as the Tome has already been tagged for destruction. Then Tome would carry out its destruction effect, searching for the sword, and then move to the trash.
Now I know your next point already. But Kismet can get healed after being destroyed with Lady Luck in play, why not the Tome in the above example? Well, this is where Ronways proposed wording change matters. Lady Luck triggers on the same wording that Ronway proposes, which is "When X would be destroyed, instead do this" sort of deal. What that actually does is postpone taging a card for destruction and keeps them as eligable targets for other effects.
Now, I guess that Ronways proposed wording would makes the interaction much cleaner and less confusing, and if that change were to be made, I wouldn't hate it.
