The meta for Moonrise was pretty healthy, all sorts of decks were viable - including Heal and Stall decks, both of which seen in top tournament decks, as well as modified starter decks because they're already built so well!
So far the meta for Firestorm is still in the kitbashing phase, new cards, new strategies, but my money's on Hestia and her Bears (Majursa and Glaciursa - the current Stellar Firestorm promos, coincidentally) being a solid choice for people that want to get into high-level play. But Pippa, if you get the Firestorm promos, please sleeve them, they will not be reprinted and will shoot up in price on the aftermarket because you could only get them throughout this month!
