As you may have seen I have recently been working on a full set of 70B and 70C trilogo cards, so thought I would write up some of my findings on the subject.
If you have no idea what I'm talking about and think there is only one type of trilogo card, the difference is that the 70C has a longer 'race track' with the copyright information on the inside in black text, rather than outside in white text. It is quite obvious when you notice it:
More seasoned trilogo collectors will tell you there are many different variations of trilogo cards such as Parker, Meccano, PBP, Palitoy etc, however in my opinion they are mostly minor regional and manufacturing variations of the same design whereas this is actually a different (albeit small) design change, so IMO is one of the most significant trilogo card variants. If you would like to know more about all the different trilogo cardbacks, check out Joe's excellent guide here.
There are 25 figures in total that are confirmed to exist on 70C cards, which is less than a third of the line. Every figure (apart from the last 17) can be found on a 70B card. It is possible there are more 70C figures out there as Nikto was only discovered recently, if you know of any others please do let me know.Star Wars
Death Star Droid
C-3PO (removable limbs)
As the two POTF Ewoks can only be found on the 70C card, I think we can assume the 70C is a later card design so older characters released on this cardback may have been reissues that had sold out and needed re-stocking. I am not sure exactly when they started being sold or where, but they come up for sale all over the place, especially in America with Kay Bee stickers.
It is important to note that 70C cards are not necessarily rarer than 70B. From my experience looking over the last couple of years, some figures are in fact much harder to find on 70B cards. Here is a list of the rarer figures on the 70C card:
Nikto (really tough, as of 2018 only two sealed examples and a cardback are confirmed)
And these figures are harder to find on a 70B card:
Death Star Droid
All of the other figures appear in fairly even numbers, or at least aren't particularly hard to find on either.
Here is a group shot of all 25 70C cards. Sadly Nikto is just a cardback due to his rarity, if I ever find a MOC example I will take another photo:

And finally here is a group shot of most of the characters available on both 70B and 70C cards together:
