After two years of broken metagames and regular bans being the norm for Standard, it appears that we are back to an ideal, dynamic Standard metagame. Yes, Esika's Chariot and Wrenn and Seven are currently a huge part of the metagame, but there are always cards at the top of the food chain, and Standard tends to be better when those cards are four- and five-mana threats that generate card advantage rather than cheaper cards like Edgewall Innkeeper or ones that create a cascading mana advantage like Fires of Invention and Wilderness Reclamation.
This new reality means that the first weeks of Standard have been relatively open and diverse, as players scramble to explore not only the cards from Innistrad: Midnight Hunt but also to reevaluate surviving cards from older sets that may now have a chance to shine. There are several decks performing well right now, and different versions of the same archetype that we have yet to definitively separate from each other.
Inevitably, some of these decks will lack the staying power to compete once the format becomes better-defined and the decks are well-tuned. Others will prove their mettle and stick around to become major players for the next few months at least. If you're looking to get into Standard right now, here's my opinion on which decks are worth buying into, and which decks you should sell high on now.
