Glad to see you've been preparing! I'm a little disappointed in the released p2e rule set, but on the bright side, it means you only need one deck of shines for max earning. That means you don't absolutely have to have wildfire and hunting trap at meteorite.
My plan is to play my best/shiniest deck for the first three wins. Then I may toss in some other decks if I've built up some MMR cushion in Mythic.
I still need to do some quick math, I probably will not care during the first week or two, to understand what makes more sense and if I should invest GODS in minting cards or not.
Maybe a meteorite deck will be good enough.
I need to understand the ROI of minting cards to increase the deck points and how much that will translate in rewards. I probably will try to use a full meteorite deck in the first days to get some kind of baseline and then add some shadows to it, maybe golds (don't have many of those) to see how it differs
