Giratina English and Japanese only list completed for someone on reddit: a total of 82 English/Japanese TCG cards, and four more featuring a Giratina in its artwork.
And I’ve been thinking about starting a list of all cards featuring multiple Pokémon, which would save me trouble in the long run. But not sure yet when I’d start that list (and it will probably take months to finish, haha). Just something I’ve been thinking about.
But I’ll first finish my W.I.P. Yu-Gi-Oh Rarities article, which will also take a few more weeks/months. 
Greetz,
