I have to say- I agree with @bronko, completely.
"accounts with a completely normal deck and no harmful behavior will have to rent CP unnecessarily. This doesn’t make sense"

Setting up another, completely arbitrary, hoop for accounts to jump through- in order to play or earn, doesn't make sense.
Especially in a format called "Wild"

That said- I fully support any proposal to institute Barriers to Entry for new players. The more complicated, involved, arbitrary, and esoteric the barrier is, the better.
