Okay, so I've looked over the cards and thought it through a bit more, and it looks like there are very few ways to land a stagger on more than one creature at a time, there's only one creature in the game that can land a stagger with a ranged attack (with the exception of the mages with their attack spells) and you can guard a minor buddy, or protect them from stagger attacks with things like Dodge. And staggers aren't as easy to land as they seem at first. There's no equivalent of akiro's favor in Academy, the genie only gets three wishes, the highest chance of stagger is the Lightning jolt's 5+ chance of stagger, and since it's an attack spell it gets discarded after use, the only ranged stagger attack has a 7+ chance of landing a stagger, which is 50% chance. And Akiro's game is epic and only works on the highest-costing creature on the board, and higher costing creatures tend to be higher level.
So minor buddies might be a viable option after all.
As for coming up with spellbook ideas being more like a word search than actual design, that's still kinda disappointing, but I hope that it will get better as more cards are released.
Also, for those who've played a full game of Academy (not just the demo), how does the gameplay compare with Apprentice mode?
