EDIT: Also, in the case of buying a G1 Ironhide and Ratchet (or any original TF for that matter), you're not really buying a "representation of the character" so much as you're buying the "toy the character is based on".
Habro used the cartoon and comics (with character designs by Marvel) to push the toys. When I was kid, I generally wanted toys characters from the cartoons or the comics. And, I wanted the toys to look like the fucking characters that I liked from the cartoons and the comics. Yeah, package art is important. But, I was looking for a toy, not for packaging. (Aside, I really cannot recall Ironhide's or Ratchet's package art.)
Frankly, most G1 toys were not good enough to be worth buying on their own.
Okay, back on topic:
The blind buy pony packages have number stamping that can be used to figure out which pony is in the bag. The numbers are part of a 5 digit code on the back-flap of the baggie. The numbers are heat-pressed, but not inked. This makes them a bit more difficult to read than I would like. But, it can still be done.
The numbering works like so:
The first, and easiest, step is to figure out which series is on shelves. (There are four at the moment.) Each pony has a number, (say, 1 - 20). That number is incorporated in to the 5 digit code listed above. The first, third and fifth digit places are filler. The second and fourth digit places are the parsed pony number.
For example: The blue bag series default code is 8_2_6.
A complete code might look like 80236
80236
The second and third numbers are "0" and "3". This translates to "03".
"03" translates to Trixie in the blue bag series. (For the record, Prowl wants Trixie, so if anybody finds a Trixie, let him know.)
The blue bag series consists of metallic or sparkly ponies that would likely be chase variants in other lines. These are really no so good if you just want a representation of a given character. But, in theory, they can be good customizing fodder.
I ended up with Rainbow Dash (19) Chance-a-Lot and Twilight Sky.
I grabbed Rainbow Dash because she is one of my favourite characters. (She barely beats Twilight Sparkle, but does not quite beat Fluttershy.) At the very least, I wanted the card. On a related note, Fluttershy is consistently a recolour of Rainbow Dash. This means that there is no good toy or Fluttershy available. (The Rainbow Dash mould does not work well for Fluttershy. The pose and mane are wrong.)
Chance-a-Lot and Twilight Sky are male ponies that I picked up for customizing. Their numbers are 6, 10 and/or 17. I really did not keep track.
The glittery ponies are....eh. Despite being moulded in translucent plastic, the figures do not let much light pass through, larger for being over-saturated with glitter. (The figures almost look to be chromed like something Takara would produce.) The glitter is externally applied, which gives the figures a "gritty" feel. If anybody is planning to use these figures for customizing, it would probably be better to select for smoother "metallic" figures, rather than the glittery figures that will need to be scraped before being painted.
The cards are really not worth buying these packs for. One side of a card is a non-numbered and visual (partial) check-list of other figures in the set. The other is a picture of the included pony along with one or two sentences about them....surrounded by plenty of dead space. (Even if the card art was of "normal" Rainbow Dash, rather than of "glittery" Rainbow Dash, I would not be able to say the cards are worth getting.) It is also worth nothing that attempts at bag feeling or even clumsy number checking can bend/crease the cards. The cards I got are all fine, but I could feel creases in other cards through the packaging.
The official theme for this set is "Crystal Empire". I am really not sure how I feel about political, to say nothing of Imperial, ponies. But, apparently, this is also going to be the "thing" for the show this year. I dunno......
