I play from muscle memory, which I don’t know if Anki will help with, unless you visualize yourself playing the scales.
If you know the shapes of those five chords (C, A, G, E, D) in open position, you probably already have them memorized in every key.
One idea: play them through using the circle of fifths:
Fat Cats Give Dogs An Endless Battle
and:
By Eight All Dates Get Cold Feet
So, first play F in all the positions. Then C in all the positions, then G, etc…
Just an idea to experiment with. I haven’t played guitar in about three years because of a hand injury.
