For example, getting a free 3/3 creature token over and over again lets you use it to power the kind of sacrifice-based strategies you often find in black (even Proliferating again if you use Throne of Geth)

Each one has its own way to trigger the spellbook, whether its upon the spells resolution or as a triggered ability

More of these should pop up as players receive and open their Secret Lairs
