(1) MD gets cards ~8 months after ocg (with the rare exception of simultaneous release), (2) the secret packs (e.g. azamina secret pack) can range from ~6 months after it's inital MD introduction, though some archetypes took an entire year. (3) The game is pretty generous with new player gems, you can pretty much craft any deck in 3-7 days if you know what you're doing (your second deck will take much longer, about 1-2 months if you do events and dailies), so my advice is settle on a deck, figure out optimal odds for secret pack pulls, start ripping, just take the good shit you get from your initial pulls through solo mode, and even do rookie - silver with your piece of shit half deck pile (its really easy mostly bots) and that will get you a bunch of gems to nearly complete your deck, usually I get the final pieces from doing SR to UR conversion (lots of explanation for this with a quick google):

First craft the cards that appear in 3 packs, then 2 packs, then later (i.e. months later, so not relevant for new player) you can start crafting for the "Packs with no good SR to craft". Here's a tip, make a copy of the sheet ctrl+a -> format -> conditional format. Create filters for every pack you have opened to keep track of what you've crafted so far: See pic related.

like the other anon said, the free friend code branded deck is a solid option for blasting solo mode/low ranks too.
