For streamers, the updated card order will make it easier to show the rarest cards at the end of each pack opening
Warriors, Dragons, and Plants are hiding in the Machines Looking throughout the market, there are so many cards that gain value over time, even if they never see a reprint, if they are a part of a past format, or if there are new tech discoveries that appear over the recent weeks from the OCG/TCG, Genesys, and even Master Duel
You will also want these to have a good curve, favoring cheaper creatures over pricier ones so you can put more onto the board quickly
Sabin, Master Monk: A recurring consistent threat, as blitz is a great mechanic with Shadow, and Sabin can blitz from the graveyard
While this usually works out to be between 4 and 6 cards, if you play fewer creatures, dont be afraid to add more board wipes to keep more creature-heavy decks off your back when needed
Note that nothing in the format resists Fire, so Eviolite is the only thing you have to worry about affecting your damage in a negative way (Special Metal is irrelevant because Entei overkills Metal, no one runs Defender, Donphans Exoskeleton doesnt prevent the 2HKO, etc.)
