English RNA is printed in the USA and Belgium. If you're in the USA, probably you're getting made-in-USA product. If you're in the UK, probably you're getting made-in-Belgium product. I'm not sure about other regions, but it will say in the fine print on the booster pack.
First, let's do a short overview of US product. There are four common print runs, A, B, C1, and C2. Packs have 2xA + 2xB + 6xC1 or 3xA + 2xB + 5xC1 or 4xA + 2xB + 4xC2 or 4xA + 3xB + 3xC2 or 4xA + 4xB + 2xC2. Foils can displace a common from A, B, or C2 depending on rarity. (It won't create a gap in the sequence, the sequence will just be shorter.) Foils only displace A if there were 4 to begin with (so 1xA is not possible even if there is a foil).
A is white/blue/red and B is green/black which helps you get a common of every color in most packs, but unlike GRN, there are now some multicolor cards in A and B.
Runs are mutual exclusive except one card appears in both C1 and C2. This card is also short-printed. Here, that card is Senate Griffin.

Now, a quick overview of Belgian product. Packs will have 6 cards from A followed by 4 from B. A foil can shorten either run by one card. There is a strong color pattern in A, but again, unlike GRN, there are some multicolor cards in A as well.
Again, the runs are mutually exclusive except for one card which is also short-printed. For this printing, it's Grasping Thrull.
First, let's do a short overview of US product. There are four common print runs, A, B, C1, and C2. Packs have 2xA + 2xB + 6xC1 or 3xA + 2xB + 5xC1 or 4xA + 2xB + 4xC2 or 4xA + 3xB + 3xC2 or 4xA + 4xB + 2xC2. Foils can displace a common from A, B, or C2 depending on rarity. (It won't create a gap in the sequence, the sequence will just be shorter.) Foils only displace A if there were 4 to begin with (so 1xA is not possible even if there is a foil).
A is white/blue/red and B is green/black which helps you get a common of every color in most packs, but unlike GRN, there are now some multicolor cards in A and B.
