Yeah, really hope there could be a good way to distinguish between them all.
I have seen so many of these onomatopoeia words and get them all confused and basically just guess every time - I’m probably getting worse at knowing which one is which every time I encounter one in the SRS system 
Sweet link! I knew that website had to have some use or another! 
Are we still getting decks for the A lists?
A1 Deck | Bunpro
A2 Deck | Bunpro
A3 Deck | Bunpro
A4 Deck | Bunpro
A5 Deck | Bunpro
A6 Deck | Bunpro
A7 Deck | Bunpro
A8 Deck | Bunpro
A9 Deck | Bunpro
A10 Deck | Bunpro
A11 Deck | Bunpro
A12 Deck | Bunpro
A13 Deck | Bunpro
A14 Deck | Bunpro
A15 Deck | Bunpro
A16 Deck | Bunpro
A17 Deck | Bunpro
A18 Deck | Bunpro
A19 Deck | Bunpro
A20 Deck | Bunpro
They all exist and you can use them but they aren’t formalized with deck art etc.
It’s great to be able to access the decks!
I’m wondering if there was any particular way of deciding what went in each “A” deck, or was it effectively random?
For example, it seems when looking through that katakana words can appear in any of the decks, but they’re usually in the earlier units 
The order is alphabetical which is why those would appear at the start.
There also isn’t any logic behind what is in A1 versus A20, they are just words. That being said, we started from A1 for making sentences so the lower decks have sentences while higher decks wouldn’t yet.
