Power wise it is low and themewise it is poor too
You chain rituals, recast tutors, rebuild your resources, and convert that storm of spells into a win before anyone untaps
One thing Ive found through playing Narset, Enlightened Exile is that it can be a tricky card if your opponents dont pay proper attention to it
For example, if a card exiled with Norin's last ability is a creature card without flash, you may cast that creature spell only during your main phase while the stack is empty
The abundance of mana dorks, token creation, and aggressive attackers make it the perfect color combo for players that want to flood the board with creatures and start turning them sideways
Regardless of why or how it does it, or if you love it or hate it, it's impossible not to take notice of it
