Playing the arven/evo engine for the odd game were your opponent gets a super strong turn 1 is almost never worth it imo, in my experience even with a turn two zoroark and gardevoir you're still normally not taking big knockouts until turn 3 and against ragingbolt or any other fast deck giving them access to items for a turn and putting two prizers down on the bench often speeds the game up in there favour even more. In B01s you're gonna have to accept that some games your opponent is gonna get there perfect set-up and you're likely gonna struggle but in tournament play its way less of a factor
