Notes & Combos
extra deck hardly comes up, aside from the hugin, obviously, and occasionally munin (especially during vs timelord games)
knightmares are cool to have, but just about everything else can be retooled as desired. kaleido is only in as a potential waking target, alongside gryphon and diviner (if you can manage to reshuffle a miller back, or just have one left in deck still)
exchange is mostly so agido can mill 10 off the opponent's deck, though kelbek being able to recover a milled trap is always nice as well. also awakening could be easily dropped for anything else of choice. probably a second smiting storm, imo, just for more access to runick spells with a usually live banish effect past turn 1. I just use awakening as a funny tech option to counter the anti-backrow counters (I was running 2 before, but I feel like the deck does a decent enough job at protecting its backrow between the solemns and hugins to make running any more than a single copy not very worth it)
