I feel like this take isn’t that unpopular. They print way too many rainbow cards and it ends up inflating the set number. If they do continue to print them I think only 1 or 2 rainbow rares in a set would work, similar to how the gold cards are.
The people with access to cards THIS eary before a set releases are not getting access to them to playtest, they are making a profit off of them and scalping them to people that want them early. Pretty sure the Silver Tempest leaker stole his lot.
Nah dude look at what happened to the Celebration UPC price. Even while it was still being sold for 120 retail you couldn’t find it for less than 250 resale.
