This is a modified version of the deck "Katakana with stroke diagrams and audio". You can find the original shared deck page
here
Changes are as follows:
1. Only includes katakana, dakuten and handakuten. Removed yōon
2. Includes a reverse card for every card:
a. Romaji + Sound => Katakana + Stroke Order AND
b. Katakana + Stroke Order => Romaji + Sound
3. Does not display hiragana
My recommendation for studying is for the cards that show the Romaji + Sound, draw the katakana with your finger before flipping. For the cards that show Katakana + Stroke Order, say the pronunciation out loud before flipping.
