If it goes right it's the best game ever. Pity it doesn't always go right, but with a Loyalty Deck mechanic you have to take these things in stride. Annoying when you play 2 hours only to find the last half an hour is boring, though.
Chaotic fun that can be done within 45 minutes. Great with 4 or 5 players, and everyone has a blast trying to figure out who goes first and how the spells interact with each other. Better than Citadels in that getting screwed doesn't really ruin the entire turn, also turns are faster and there's less downtime. Also I've found less AP when picking spells as opposed to the character draft.
Brilliant game, dynamic, extremely unfiddly, and so many layers of strategy. I've only scratched the surface of what this has to offer and already I'm completely hooked. This is number 1 on the Geek for a damn good reason.
