I prefer putting everything into one big deck for a few reasons.
It forces you to do all the cards every day. When I had different decks, I would do the “main” deck every day, but then not do the other decks.
I have not read any research on this, but it seems like interspersing the cards could make the cards less likely to anticipate and force you to learn better.
It also just mixes up the monotony and makes it more fun.
