Like if you want the non-tinfoil theory about deck matchmaking the "Collector Level" element of the matchmaking calculation is weighing in the collector level you obtained the cards in your deck rather than overall collector level.

In which case yeah you can trust the devs (if they're not lazy and are tracking the right data) to have properly tested it

Personally I see enough benefits to intentionally rigging up the matchmaking that I assume it's working as intended, but SOMETHING is definitely going on with it because there are way too many people noticing it for it to just be "oh no that's just how the randomness in the matchmaking is"
