I get the sentiment of the changes and overall agree. The only feedback I would have is to not make the collection score requirements too large. The goal should absolutely be to hold the “spam” play to the lower tiers but there should be very little distinction between the score requirements for higher tiers. If someone can skillfully play lower ranked cards and beat opponents with a higher collection score, they shouldn’t have the feeling that there is a “paywall” to advance into the next tier.
