That's a bit suspicious. If they also do the rare ICRs I wouldn't be surprised if they try to jack the price up on it. Those might just be the juicy packs, they said 31 new cards and 700-something cards total, Jumpstart packs are typically 20 cards (Including lands) so 31x20 comes to 620 which isn't completely accurate since, again, that's counting land in the packs while WotC would be talking about non-basic land. So they can't fit a new rare and an old rare into every pack.spot checks shows that jumpstart packs appear to have 1 new rare and 1 existing?
Edit: Also depends of course on if they do the pack variants like they did with regular Jumpstart. There would be the big money rare and mythic packs but there could be some good variations on common packs if you highroll for the best one. Which ideally someone does a nice spreadsheet for this like they did on vanilla Jumpstart since that was really useful.
