Simply, Radical is small component which kanji is made of. (Heisig called his own radicals as primitives)
Learning radicals is essential if you want to learn kanji faster and in a better way.
This deck contains all of 214 radicals ordered by usefulness (popularity) with english meaning, reading, stroke information, example and alternative forms (if available).
Remember to check out the examples, as some radicals only appear in alternative forms instead of original form (like 辵, 艸, 阜, etc). You should notice the position of the radical in the example kanji too, because each radical usually has only one or a few possible positions in a kanji. Please also note that each position may have different reading, such as the "person" radical (人) at top is called ひとやね (like in 会) and is called にんべん if it's at the left side (like in 体).

Note: For stroke order working, download and install font from this:
http://www.nihilist.org.uk/. You just need to download the font file, which is KanjiStrokeOrders_v3.001.ttf , then install it.
If you're using android phone, put the font in /sdcard/AnkiDroid/fonts (you may need to create folder "fonts").
If the font doesn't work, try renaming it to "KanjiStrokeOrders" (remove the "_v3.001").
Update Sep 10:
-Reorder the whole deck "by-hand" (based on some sources like wiki too). Now the most useful radicals will appear first.
-Added example kanji for each radical.
Update: Correct reading for radical 牛 (Thanks for your comment). I'm pretty sure there won't be any other errors with readings. (And also, I added readings to this deck for reference purpose only, you don't need to remember these readings, just remembering the meanings is ok :D).
PS: I've made a kanji deck too. You can check it out here:

PS (again): For those who don't get the "odd" order, please have a look at this:
http://www.kanji-link.com/en/kanji/intro/ . The first 48 radicals in this deck was ordered to match 48 most frequent radicals in that website (which help you cover 75% of Joyo Kanji). The rest was ordered by me as I've gone through 214 radicals and have a "sense" that which radical is popular than the other. Many of you may agree with me that some radicals that have less strokes may be almost never seen (like 瓦,耒,尢,屮) , so I put them to the bottom of the list. Of course, if you want to master all 214 radicals then the order is not matter anymore, just learn them all.
Reply to the comment saying this deck is chinese, not japanese: I'm not sure what you're trying to express here??? Everyone knows both chinese & japanese use Chinese characters, there're some differences between the two versions of the two languages but in traditional form, they're the same (called 'kyuujitai' in Japanese, fyi). But that has nothing to do with radical, as the 214-radical system apply to both languages (some radicals are simplified in chinese though, but still 214), and this IS a radical deck, not a kanji deck. Anyways, thanks for your comments from that I can improve the deck, just hope you can clarify your idea :).
