I really do adore how everythings been implemented, in the same way I loved how Dungeons & Dragons was woven into Adventures in the Forgotten Realms, but I think the power level of the set is a bit mixed when it comes to the new mechanics, despite there being some very powerful cards in Innistrad: Midnight Hunt to flashback and some good creatures and planeswalkers, too
Kalonian Hydra, Sovereign Okinec Ahau, Innkeeper's Talent, and Maester Seymour all help us rapidly scale up our board with +1/+1 counters
For example, Everlasting Torment can make Circle of Protection: Black sit there uselessly in play, while Spirit of the Labyrinth effectively blanks a number of "draw a lot of cards" decks
Does a Mana Curve Include Lands
If youre leaning into the self-mill aspect of the deck, the classic Altar of Dementia plays well with large unearthed creatures
