This is a departure from Remastered sets in the past
You can then tap them to take a face-down attacking creature and turn it face-up, completely skipping any cost that they might require
I think expecting it to wiff entirely a third of the time is reasonable
Because Breena is so efficient at loading up on +1/+1 counters I've leaned into it with a strong counter subtheme: we use those counters to draw cards off Dusk Legion Duelist, ramp with Scholar of New Horizons, have board wipe insurance with Felisa, Fang of Silverquill, and turn our team into lethal angels with Sigarda's Summons
Generally speaking, there should always be more cost 1 cards than cost 2 cards, more cost 2 cards than cost 3 cards, and so on and so forth
It just so happened that both sets were being printed in the same facility
