I think that Rider decks that are just recoloured are unjustly being called clones e.g. Albano-Waite. In my opinion, a Rider clone is more like Hanson-Roberts or Morgan-Greer.
There are many decks that get the label of being a Rider clone. But in my opinion, there are different categories. A lot of decks have some RWS influence, but would not really immediately be a clone. I personally divide the 'clones' up in:
- re-coloured (using same line art, but different colouring)
- re-drawn (using the exact imagery, but then drawn differently or with animals or sorts, like DeAngelis, Bota, Gummibear)
-RWS-based (meaning very closely based on the RWS, like th MOrgan Greer or the Hanson-Roberts. But yet being different enough to not be just a re-drawing)
There are also a few what I call, half-clones. Where half of the deck is based on the RWS, often just the minors. The Thompson-Leng is one of those too.
The Albano-Waite is most definately a re-colouring.
