This way you can easily cram irregular verbs for basically every language. Yes, it takes a while to make such a deck. But the advantage is that you can repeat numerous verbs in a tense simultaneously because of the deck structure.
Have you thought of presenting the information as a Cloze card: i.e. each conjugated verb + pronoun is an optional Cloze. That generates 21 different cards for the card design in your first image.
This way, you are not asking for a user to understand the whole card, but to know one piece of information.
It is pretty easy to set up, if you use a spreadsheet.
But in a cloze card only one item is hidden and the rest are all visible.
However in a verb conjugation table the entries are not independent. They usually follow a pattern, so the visible parts will give away the answer to the hidden part.
So if you have, for example:
nous {{c1:aurons}}
vous {{c2:aurez}}
Then you’d have a card that looks like:
nous […]
vous aurez
But for this verb, the whole key to the future tense is simply that the stem av- changes to aur-
So with this cloze method you immediately know any answer by inspection without having to retrieve it from memory.
